AWS Lambda Execution Failed " Cannot find module '/var/task/modules/translate/src/promise" about translation-server HOT 8 OPEN

Thanks, yes, the promise js file is missing. I will add, and let you know the outcome.

The previous deploy script copies over submodules into a new dir named package. It seems possible that your submodules weren't pulled in locally before deploying! Try running git submodule update --init --recursive before running locally and deploying.

See line 18 which copies the modules dir (containing multiple git submodules):

Thank you SevanBadal. I will follow your directions and I will let you know the outcome

from translation-server.

The modules were copied and the problem still persists. My lambda deploy file is shown below:

#!/bin/bash -e
dir="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"

if [ -z $1 ]; then
	echo "Usage: $0 config.env" >&2
	exit 1
fi

set -a
. "$dir/$1"
set +a

rm -rf package
mkdir package

# Skip files that aren't required i.e. ".git"
cp -r config package/
cp -r modules package/
cp -r node_modules package/
cp -r src package/

# Remove broken symlinks because "sam package" complains
find -L package/ -maxdepth 10 -type l -delete

Can you please paste the result of ls modules/translate here? We want to confirm that the translate directory is not empty.

I'm not seeing promise.js in the contents of your modules/translate/src directory! This could be related to the error message you reported above which is complaining about not finding a module /var/task/modules/translate/src/promise:

I deployed the zotero translation-server on AWS lambda using your previously deleted lambda_deploy script. Every time I make a request via the API Gateway url the translation-server fails with a "Missing authentication token" The error logs show:

Lambda execution failed with status 200 due to customer function error: Error: Cannot find module '/var/task/modules/translate/src/promise'
Method completed with status: 502

I am tryng to redeploy, by using the updated repository. but I am stuck at ./lambda_deploy: line 15: j2: command not found The jinjacli is installed jinja2 in ./env/lib/python3.8/site-packages (3.1.2). Prior to using the updated code, I deployed with the promise module, but the same error occurred, because the function was looking in /var/task/modules/translate/src/promise for the promise module, but the promise.js file was in my home folder/translation-server/modules/translate/src/promise*. I am thinking of creating a symbolic link. I am unsure if that will work, since I am still stuck at j2 command not found. Any thoughts about the J2 command?
