PR reviewers are not always assigned

[olehm-ma]

Describe the bug
From time to time we see that auto-assign bot is not invoked into the new PR. So it remains with no reviewers assigned. The configuration of the repo was not changed:

Example:

# Set to true to add reviewers to pull requests
addReviewers: true
# A list of reviewers to be added to pull requests (GitHub user name)
reviewers:
  - user123

To Reproduce
It is rather difficult to reproduce the issue on demand. Just from time to time the reviewer is not assigned.

Expected behavior
user123 should be assigned to all pull requests in a specific repo

Seeing similar behavior and our configuration has not changed.

Reporting the same. Our configuration hasn't changed either. This has been happening on and off about 3-4 weeks now. Just uninstalled and reinstalled the App to see if that helps at all.

Recently, the application tries to use more memory and CPU than was allocated by Glitch's free tier (Glitch is the infrastructure that runs this application.). At that point, the application will be restarted automatically and may be temporarily unavailable. I'ｍ trying to find out the cause of the issue.
