Description

Expected behavior

(Using WebAPI 2.14.0 / Atlas 2.14.1)

Generated Characterization results can be returned when clicking on them.

Actual behavior

Sporadically, we see these 403 errors when trying to view the results of a Characterization:

This then becomes a problem for all users. The only workaround seems to be to simply create a new one, generate it, then view it. Somehow then this issue clears for all users.

Steps to reproduce behavior
  1. Create and generate a characterization
  2. Try to view the results, perhaps after a few days?

Research direction

No source file or test is named. Start by reproducing the characterization flow from the reported steps and inspect the request that fetches generated results, including the conditions surrounding the sporadic 403 response. Done means identifying and fixing the cause so existing characterization results remain viewable for all users, then adding or updating coverage for the failure case.
