  • An API REST on API Gateway
  • A Lambda function with a trigger on API Gateway
  • A use this lambda as an Authorizer for API Gateway

  • It's not the same problem, In my case the function is used as authorizer but not for API/method Commented Sep 29, 2021 at 13:05
  • Are you attaching an existing API to this new lambda function? Commented Sep 29, 2021 at 13:07
  • Yes, it's the same function and the same API, just I'm removing the trigger ok lambda function and I tried to recreate it a second time Commented Sep 29, 2021 at 13:16
