Hello,
We're hitting some issues with dynamic library dependencies of a lambda deployed via this library.
I included as much details as I could gather (sorry if it's too much). Any help on this would be appreciated 😃
When I deploy the lambda by running npx sls deploy and do a test run of it in AWS, I'm getting the following error:
START RequestId: 07ef6bc4-ef85-49bf-82eb-8a73a1e313c3 Version: $LATEST
./r-executor-cleanup: /lib64/libldap_r-2.4.so.2: no version information available (required by /var/task/libpq.so.5)
./r-executor-cleanup: /lib64/libm.so.6: version `GLIBC_2.23' not found (required by /var/task/libquadmath.so.0)
END RequestId: 07ef6bc4-ef85-49bf-82eb-8a73a1e313c3
REPORT RequestId: 07ef6bc4-ef85-49bf-82eb-8a73a1e313c3 Duration: 26.71 ms Billed Duration: 100 ms Memory Size: 1024 MB Max Memory Used: 6 MB
RequestId: 07ef6bc4-ef85-49bf-82eb-8a73a1e313c3 Error: Runtime exited with error: exit status 1 Runtime.ExitError
The lambda looks like this so far (but the binary has all our required haskell dependencies)
module Our.Module.Name where
import AWSLambda (lambdaMain)
import Data.Aeson (Value)
lambda :: IO ()
lambda = lambdaMain cleanupHandler
cleanupHandler :: Value -> IO ()
cleanupHandler _ = putTextLn "TODO implement me"
build environment
We tested building the lambda in couple of environments, each time the error we got when running Test in aws was the same:
- Linux 5.8.8, Fedora 32
- Linux 5.4.62, NixOS 21.03
- MacOS
We're building our project using stack lts-16.2,
we tried both with serverless-haskell 0.11.3 (included in the lts-16.2 snapshot) as well as with the latest version from hackage (0.12.1 - added to stack.yaml inside extra-deps)
Our package.json looks like this:
package.json
{
"name": "pi-haskell-lambdas",
"version": "0.1.0",
"description": "Config for building and deploying haskell lambdas via serverless framework",
"directories": {
"test": "test"
},
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"author": "",
"license": "ISC",
"dependencies": {
"serverless": "^1.83.0",
"serverless-haskell": "^0.12.1"
}
}
Addition info + things we tried:
As for the two .so files mentioned in the error log:
libpq.so.5 - is dependency of postgresql-simple that we're using
libquadmath.so.0 - this is dependency of some of the linear algebra / machine learning libs our app is using

Note that this corresponds to the error we're getting when testing the lambda in AWS console.
/var/task is owned by aws_user:1000 now, but lambci/lambda:build-provided.al2 runs as sbx_user1051, which makes sls offline start die with permission errors like not being able to access /var/task.
How can this be rectified?
Using sls yaml config:
plugins:
- serverless-haskell
- serverless-offline
custom:
haskell:
docker: true
serverless-offline:
useDocker: true
printOutput: true
Ta!
Should leave the Haskell process running and communicate to it via sockets or even HTTP requests.

Hello @koterpillar,
since amazonka 2.0 release candidate is out (brendanhay/amazonka#716)
I'd like to upgrade to it, but this will require this library to migrate to it too.
Are you planning to upgrade this library to support it?
If you're too busy, I could try opening a PR (not sure yet how much effort it would be). I opened an initial PR to help you preview the necessary changes.
Would you prefer to support both <2.0 and >=2.0 version of amazonka or would you be ok with moving to >=2.0 only?
The former would likely require lots of CPP..
I had been thinking about trying to write a wrapper process based on a node extension to address #24 and #26 but that involved a lot of strange chicanery, especially as we'd have a C shim between Node and Haskell, so it'd get gross.
If we can bind to the new C++ runtime API that seems like the easiest and best route to a genuinely native Haskell runtime.
If no one else is working on this, I'm inclined to take a shot at it, especially if it can all be done through ctypes. My inclination is to write a separate package that calls into the API rather than adding to this, unless it winds up needing some of the types already nicely defined here.
Any thoughts?
Today I tried upgrading from serverless-haskell from 0.12.5 to 0.12.6
With 0.12.5 my lambdas are building fine.
But after upgrade to 0.12.6 I started getting failures like this:
...

Hi. New to Serverless so maybe I'm doing it wrong, but:
Steps
- Check out and build example project
- Verify that
sls invoke hello -d "[1, 100, 10]" correctly returns "Highest value is 100"
- Then run
sls invoke local hello -d "[1, 100, 10]"
Expected
- Same result, i.e.
"Highest value is 100"
Actual

Hi,
I wonder if it would be possible to add support for serverless-offline. It would be awesome to be able to develop a haskell lambda locally with all the available plugins. :)
Whats your opinion?
Thanks!
I'm currently getting this error from my AWS apigateway api using Postman:

My json payload is as follows:
{ "resource" : "/updatepic"
, "body" : "pleasework"}
My end point is: https://xxxxxxxxx.execute-api.us-east-1.amazonaws.com/dev/updatepic
I'm not sure if I'm formatting my JSON payload correctly. I've tried many variations but I'm getting timeouts and the bad JSON error above.
If I don't put any payload in my POST request my lamba function continues to execution and outputs "not enough input"/
This is my "event" JSON parser:
instance FromJSON Event where
parseJSON = withObject "Event" $ \v -> do
bd <- v .: "body"
rs <- v .: "resource"
pure $ Event bd rs
And this is my serverless.yml

Hey there - first off: thanks for this nice techology.
Unfortunately I now spent two hours and could not get it to work. I tried cloning the example project and creating one from scratch. I always run into the following error:
~/example-project
❯ sls invoke local -f hello
Serverless: Package version mismatch: NPM: 0.7.5, Stack: 0.6.7. Versions must be in sync to work correctly. Please install matching versions of NPM and Stack packages by either pinning your NPM version to match stack, or adding an extra-dep in your stack.yaml to match the NPM version.

Package version mismatch.

Your Environment Information -----------------------------
OS: linux
Node Version: 8.12.0
Serverless Version: 1.32.0
Note: I am fairly new to haskell development.
I tried
- adding
extra-dep to stack.yaml but the npm package was not found in the registry. Downgrading to an old version of NPM was not straightforward plus I do not get why the version of NPM would be relevant. Is the message maybe referring to NodeJS rather than NPM?
- Why do I need a realy old version of stack for this to work?
It would be nice if the example project would be working with the latest or modern versions of stack and node.
- I could not find documentation on the error message.
- I have no clue what to sync with what as I could not find configuration pointing to the versions mentioned in the error message.
After adding ld-options: -static -pthread to my .cabal, sls deploy fails in the stack build step with no error message. During the build, stack issues a bunch of warnings like Using 'getprotobyname' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking", but no actual error messages. Yet for whatever reason the process returns status code 1.
Odder still, when I change the fail condition in the runStack function from result.status > 0 to result.status > 1, the executable gets deployed and runs successfully.
Considering that static linking is often necessary for deployment to serverless, there should be some better handling for this case, and we should also look upstream to figure out why stack is returning an error code.
There's a fairly standard set of types for these defined https://hackage.haskell.org/package/http-types. wai (Web Application Interface) depends on them directly. Beyond the general benefits of standardization, using the standards here would make it slightly easier to package up WAI applications for use with API Gateway.
Here's a rough draft of that:

Thanks for the great library. I am looking a way to run serverless-haskell in Google Functions instead of AWS Lambda.
Aws Lambda with custom runtime support makes it pretty easy to create runtimes aside with officially supported languages. Google Functions doen't have custom runtimes support and I am trying to figure out if running haskell is even possible.
Do you have any idea on how to achieve this?

Disabled serverless-haskell in nightly build for now.
It would be good to document whether this project is restricted to aws lambda or if all serverless cloud providers are supported (and which ones are tested).
Only the same versions of the serverless plugin and the Haskell package are guaranteed to work. Updating the one means updating the other. Need to:
- Document this
- In serverless plugin, check the Haskell package version (
stack list-dependencies --depth 1 | grep serverless-haskell)
The readme is good, but it doesn't explain what happens during deploy. Which ghc version is being used? Is ghci used? Which build systems are used? Cabal or stack?
I'm trying to deploy the example project, but it fails given that Ubuntu 18.04 is shipped with glibc 2.27, so when invoking the lambda it complains that it cannot find it.
Any ideas on how to fix this? Is there a docker image available for building this properly?

Sorry for raising another issue, but I can't really explain what is going on.
I have used the stack template to create a new project and updated the resolver to lts-13.19.
I can run the function locally without any issues and deploying it worked also fine.
Unfortunately, running the deployed function times out.

I have played around with the deployed javascript file and it seems like waiting for the server is the culprit.
const socket = await connection;
I have put return { statusCode: 200, body: JSON.stringify('Hello from Lambda!')}; before this line and the lambda finishes fine. If I put it after awaiting the connection it times out.
Not sure if anyone can reproduce this or knows what I am doing wrong?
This is just an idea / feature request.
I have been playing around with serverless-haskell for a few days now and it works quite well.
The only issue I can see is using it with continuous deployment.
I use Gitlab CI and I would love to be able to split building and deploying into 2 build steps.
This would require being able to invoke serverless deploy without building, but using an already built binary.
So basically I would love to be able to
- Build without docker
- Deploy binary built in step 1
Of course there might be a better way of doing this, it was just an idea I've had.
I am also willing to help building this if you think it is a good idea.
I belief you intend to Port this to Google, but they released cloud run which is serverless on containers. Between that and anthos, will delivering Google offering become priority.
Im not in love with aws, because of the above, aws doesnt deserve it :p.
serverless-haskell should add all dependencies of a handler by default, and should allow the user to ignore dependencies if needed. This would make configuration easier.
I have made a fix which does this. I can make a pull request for this if desired. The ignoreLibraries are added to the IGNORE_LIBRARIES list.
