[PR #646/4b124547 backport][stable-3] Handle ResourceNotFoundException while iterating certificates #657

@patchback patchback bot commented Feb 9, 2022

This is a backport of PR #646 as merged into main (4b12454).

SUMMARY

The module/utils/acm.py was not correctly handling deletion of certificates. While iterating over a list of certificates, the get_certificate function was making API calls to obtain more information about the certificates, but some certificates may be deleted while iterating.

Fixes #622

ISSUE TYPE
  • Bugfix Pull Request
COMPONENT NAME

acm.py

ADDITIONAL INFORMATION

Wow, it seems many tests are very flaky. I'm attempting to fix an issue in ACM, but problems occur elsewhere. Not to mention I raised this PR to fix #622, which was discovered while working on ansible-collections/community.aws#870. And I discovered other issues as well, and so it looks like it's not possible to make any progress without going down a tree of bug fixes.
