ADDITIONAL INFORMATION
Amazon appear to have dropped support for creating Python2.7 lambdas:
botocore.errorfactory.InvalidParameterValueException: An error occurred (InvalidParameterValueException) when calling the CreateFunction operation: The runtime parameter of python2.7 is no longer supported for creating or updating AWS Lambda functions. We recommend you use the new runtime (python3.9) while creating or updating functions.
