module fails with TypeError: a bytes-like object is required, not 'str'

[rituparnop]

SUMMARY

This issue is there for 2-3 years now I guess. There is an issue with Boto "connection.py" for SSL Proxy with string headers (suppose to be encoded). As "amazon.aws" uses boto and not boto3 (like community.aws) so its fails in env where SSL Proxy enabled.
Refer below issue links.
