Errors

• ServiceException:

  The AWS Lambda service encountered an internal error.

• ResourceNotFoundException:

  The resource (for example, a Lambda function or access policy statement) specified in the request does not exist.

• ResourceConflictException:

  The resource already exists.

• TooManyRequestsException:

  Request throughput limit exceeded.

• InvalidParameterValueException:

  One of the parameters in the request is invalid. For example, if you provided an IAM role for AWS Lambda to assume in the CreateFunction or the UpdateFunctionConfiguration API, that AWS Lambda is unable to assume you will get this exception.

• PolicyLengthExceededException:

  The permissions policy for the resource is too large. Learn more

• PreconditionFailedException:

  The RevisionId provided does not match the latest RevisionId for the Lambda function or alias. Call the GetFunction or the GetAlias API to retrieve the latest RevisionId for your resource.
