ResourceInUseException The operation conflicts with the resource's availability. For example, you attempted to update an EventSoure Mapping in CREATING, or tried to delete a EventSoure mapping currently in the UPDATING state.
ResourceNotFoundException The resource (for example, a Lambda function or access policy statement) specified in the request does not exist.
ServiceException The AWS Lambda service encountered an internal error.
