Bug: sam delete raising error

[Thomas-McKanna]

Description:

Periodically, I get an error when trying to delete my SAM application. I don't know what conditions cause it, unfortunately, but I've pasted my traceback below.

There was a similar issue in the past the got closed (#5955), but it seems this is still an issue.

Steps to reproduce:

Run sam delete. The issue is flakey, and sometimes I am able to delete my SAM apps.

Observed result:

Hi @Thomas-McKanna, thanks for raising the issue. It seems you are using SAM CLI v1.97.0. Can you please upgrade your SAM CLI to v1.99.0 or above? as this comment mentions the fix was released in v1.99.0

[Thomas-McKanna]

Good call. Closing issue.
