Current Behavior
With the following configuration
- Localstack Pro running in a Docker container on port 4566
- A Cognito User Pool (id: us-east-1_userpool)
- Lambda PostConfirmation trigger configured
- Username attributes includes email
- AutoVerifiedAttributes includes email
- A Cognito User Pool App Client (id: userpoolclient)
- A Lambda (arn: arn:aws:lambda:us-east-1:000000000000:function:local-cognito)
- This lambda should log out the event and then return with a successful response
- An email - aj@email.test
- A password - abcdefg987
Run these commands
aws cognito-idp sign-up --client-id userpoolclient --username aj@email.test --password abcdefg987 --region us-east-1 --endpoint-url http://localhost:4566
# Get the UserSub value from the prior command's output and replace ##UserSub## in the next command
# From the localstack container, get the confirmation code from the logs and replace ##ConfirmationCode## in the next command
aws cognito-idp confirm-sign-up --client-id userpoolclient --username ##UserSub## --confirmation-code ##ConfirmationCode## --client-metadata '{"testing":"true"}' --region us-east-1 --endpoint-url http://localhost:4566
Look at the lambda logs and observe that the event log includes clientMetadata: {}:
{
"version": "$LATEST",
"triggerSource": "PostConfirmation_ConfirmSignUp",
"userName": "##UserSub##",
"region": "us-east-1",
"userPoolId": "us-east-1_userpool",
"callerContext": {
"awsSdkVersion": "aws-sdk-unknown-unknown",
"clientId": "userpoolclient"
},
"request": {
"validationData": {},
"clientMetadata": {},
"session": [],
"userAttributes": {
"email": "aj@email.test",
"sub": "##UserSub##",
"email_verified": "false",
"cognito:user_status": "CONFIRMED"
}
},
"response": {}
}
Expected Behavior
clientMetadata should be {"testing":"true"}
{
"version": "$LATEST",
"triggerSource": "PostConfirmation_ConfirmSignUp",
"userName": "##UserSub##",
"region": "us-east-1",
"userPoolId": "us-east-1_userpool",
"callerContext": {
"awsSdkVersion": "aws-sdk-unknown-unknown",
"clientId": "userpoolclient"
},
"request": {
"validationData": {},
"clientMetadata": {
"testing": "true"
},
"session": [],
"userAttributes": {
"email": "aj@email.test",
"sub": "##UserSub##",
"email_verified": "false",
"cognito:user_status": "CONFIRMED"
}
},
"response": {}
}
How are you starting LocalStack?
With a docker-compose file
Steps To Reproduce
How are you starting localstack (e.g., bin/localstack command, arguments, or docker-compose.yml)
docker run localstack/localstack-pro:3.8.1
Client commands (e.g., AWS SDK code snippet, or sequence of "awslocal" commands)
aws cognito-idp sign-up --client-id userpoolclient --username aj@email.test --password abcdefg987 --region us-east-1 --endpoint-url http://localhost:4566
# Get the UserSub value from the prior command's output and replace ##UserSub## in the next command
# From the localstack container, get the confirmation code from the logs and replace ##ConfirmationCode## in the next command
aws cognito-idp confirm-sign-up --client-id userpoolclient --username ##UserSub## --confirmation-code ##ConfirmationCode## --client-metadata '{"testing":"true"}' --region us-east-1 --endpoint-url http://localhost:4566

I tried this with the latest Docker image tag a few days ago and got the same result.
I have confirmed that this setup works as expected in AWS.
