I have a problem while using the Serverless framework to deploy my stack to AWS.

I’m running this serverless deploy --stage tst --region eu-west-3 --verbose

Then 2 of my functions get stuck in “CREATE_IN_PROGRESS” then 1 hour later, I have a “UPDATED_FAILED_ROLLBACK_IN_PROGRESS” and “UPDATED_FAILED_ROLLBACK_COMPLETED” status.

 CREATE_IN_PROGRESS - Custom::S3 - MyFunctionDataListenerLambdaCustomS31
 CREATE_IN_PROGRESS - Custom::S3 - MyFunctionData2ListenerLambdaS31

Here is one of my yaml function definition :

MyFunctionDataListenerLambda:
  name: myapp-${sls:stage}-entry-data-listener
  description: 'Triggered by S3 event and start a new step function execution'
  handler: src/features/entry/infrastructure/lambda/myapp-files-listener/handler.handle
  role: MyAppDataListenerLambdaRole
  layers:
    - ${ssm:/${sls:stage}/utils-lambda-layer-arn}
  events:
    - s3:
        bucket: myapp-${sls:stage}-data
        event: s3:ObjectCreated:*
        existing: true
        forceDeploy: true
        rules:
          - prefix: xxx/
          - suffix: .csv
  environment:
    ONE: ${self:custom.redshift.stage.${sls:stage}}
    TWO: myapp-${self:custom.redshift.stage.${sls:stage}}-redshift-cluster
    THREE: myapp
    FOUR: ${self:custom.redshift.stage.${sls:stage}}_myapp
    FIVE: arn:aws:states:${aws:region}:${aws:accountId}:stateMachine:myapp-${sls:stage}-workflow
    SIX: myapp-${sls:stage}-myapp/data

The other function is almost identical

So this problem occurs when I put the node “events”

    - s3:
        bucket: myapp-${sls:stage}-data
        event: s3:ObjectCreated:*
        existing: true
        forceDeploy: true
        rules:
          - prefix: xxx/
          - suffix: .csv`

when I remove it, everything works, the Role “MyAppDataListenerLambdaRole” is defined as follow in another file included in the serverless.yaml

Resources:
  MyAppDataListenerLambdaRole:
    Type: AWS::IAM::Role
    Properties:
      RoleName: myapp-${sls:stage}-listener-role

            Action: sts:AssumeRole
      ManagedPolicyArns:
        - arn:aws:iam::aws:policy/service-role/AWSLambdaBasicExecutionRole
      Policies:

          PolicyDocument:

            Statement:

                Action:
                  - states:StartExecution
                Resource: arn:aws:states:${aws:region}:${aws:accountId}:stateMachine:myapp-${sls:stage}-workflow
              - Effect: Allow
                Action:
                  - s3:GetObject
                  - s3:PutObject
                  - s3:ListBucket
                Resource:
                  - arn:aws:s3:::myapp-${sls:stage}-data
                  - arn:aws:s3:::myapp-${sls:stage}-data/*

I tried to put in my configuration

provider:
deploymentMethod: direct # also tried with changesets still stuck

I don’t find anything useful online, this is the first time i’m writing here because I’m really stuck with that, please tell me if you need more information. The S3 bucket is created on another project with the CDK
