Session Not Found about amplify-ui HOT 15 CLOSED

i will try to reproduce a minimum repo tomorrow, much thanks.

from amplify-ui.

Hi @zerokarafont thanks for creating this issue. Were you able to take a look at our troubleshooting guide? It outlines two common reasons for seeing the 'Session not found' error. It looks like you're setting the region to us-east-1, so double check that the backend is using the same region.

Let us know if the guide doesn't help, and we can debug further from there.

i am sure my lambda in the same region, the problem is it worked well on local dev, but not work when i deployed on aws. i have checked troublesshooting.

from amplify-ui.

Even if the lambda is in the same region, it's still possible that the region is being set incorrectly in the API calls to Rekogniton. Can you look for this line in the lambda code and see which region is getting set?
const client = new RekognitionClient({ region: <region> });

If the above doesn't address your issue, can you try removing the FaceLivenessDetectorCore component and making the StartFaceLivenessSession call with the using the AWS JS SDK instead? Like this. You can use the sessionId returned from fetchCreateLiveness. (Removing the UI component will help us better diagnose a root cause.)

from amplify-ui.

const stsClient = new STSClient({ region: 'us-east-1' }),
const rekogClient = new RekognitionClient({ region: 'us-east-1' }) it's right in code. I got other helpful case, command GetSessionTokenCommand works well locally but got Cannot call GetSessionToken with session credentials online.

package.json
"dev": "cdk synth --profile face-dev && sam local start-api --host 0.0.0.0 --port 9000 --container-host docker.for.mac.localhost --template cdk.out/*.template.json"

"deploy": "cdk deploy --profile face-dev --platform linux/amd64"

from amplify-ui.

My CDK config
const stsPolicy = new iam.PolicyStatement({ actions: [ "sts:GetCallerIdentity", "sts:GetSessionToken" ], resources: ['*'], });
const rekognitionPolicy = new iam.PolicyStatement({ actions: ['rekognition:*'], resources: ['*'], });
fn.role?.attachInlinePolicy(new iam.Policy(this, 'FaceDev', { statements: [rekognitionPolicy, stsPolicy] }));

@zerokarafont Can you please try calling StartFaceLivenessSession from your frontend using the sessionId from your deployed lambda?

I tried, not work

@zerokarafont can send us what you tried and what error message you got, and we'll try to help you get it working.

@reesscot @esauerbo https://github.com/zerokarafont/aws-liveness-issue-replay , i made a replay repo please check thanks!

hello, any update?

from amplify-ui.

Hi @zerokarafont looks like this repo is using the FaceLivenessDetectorCore component. Can you attempt a reproduction without the UI component? You can use the StartFaceLivenessSession command to call the Recognition API directly using the session Id from fetchCreateLiveness.

I believe you mentioned that you tried this and it didn't work, so if you're able to tell us what you tried and what error you got we can help from there.

This issue typically indicates a configuration issue, so using the StartFaceLivenessSession api directly will help us find the root cause.

from amplify-ui.

@zerokarafont here's a sample repo showing how to make this API call. You'll likely need to make some modifications but can you try pulling this down and see if you get the same error? https://github.com/esauerbo/rekognition-sdk-repro/tree/main

You can retrieve the required credentials by going to Isengard -> Console Roles -> Click the copy button to access AWS console/temporary credentials

from amplify-ui.

@esauerbo tried this repo https://github.com/esauerbo/rekognition-sdk-repro/tree/main, it works on my credential, but got error if i fill in sessionId from my lambda
, it seems like prod configuration problem, i have already checked all cases, dont know how to fix it.

avoid using custom credentials provider
