Triggering events from an existing S3 bucket which are read in a Lambda function (different regions)

I have the following issue:

    handler: ...
      - s3:
          bucket: myBucketName
          event: s3:ObjectCreated:*
          existing: true

My newFunct is deployed to AWS region eu-central-1. The bucket myBucketName is based in region eu-west-1

I got the following error message during my deployment process:
the notification destination service region is not valid for the bucket location constraint

If the bucket and the Lambda function are in the same region, the setup can be deployed without any problems.

Does anyone know how to solve this problem?
