Because calls to AWS REST API can be long-running (especially when dealing with CloudFormation calls) I have used asyncio
to parallelize calls, with an executor
(see here for more info).
However, when some of the calls failed (or even without failures) I get this error:
[ERROR] module 'botocore.vendored.six.moves' has no attribute 'configparser'
without any further indication (e.g., a stacktrace) to figure out what the root cause is.
