Also, the publisher portal receives an ISE error (code 500) as soon as you save the invalid access token.

Steps to Reproduce

• Follow the guide Create and Publish an AWS Lambda API.
  and follow the Using stored AWS credentials approach by creating a separate user account with both AWSLambda_ReadOnlyAccess and AWSLambdaRole permissions and enter credentials of that account.
• deprecate the access key from the AWS side/ or simply give a wrong key as the input.
• Observe the error thrown in the APIM server (terminal) and the publisher portal UI
