setting logging level for lambda function not working

[gmontagne]

lambda function is at creation set to log in txt format, ignoring the logging level set in the code: https://aws.github.io/chalice/topics/logging

suggest to add a config setting to set logging to json (or preferably standard create the lambda with logging set to json).
