SI: Occasional Unhandled Exception w/ `HccClientDependency` Class #393

Open WillStrohl opened 2 years ago

WillStrohl commented 2 years ago

Describe the bug

It's unclear why this is happening, but occasionally, the exceptions below are seen and could create a fatal error to crash the site in some cases.

Software Versions

To Reproduce

Steps to reproduce the behavior:

  1. Install and run the site
  2. Sit and wait... 🤷🏽‍♂️

Expected behavior

The site just runs without exceptions.

Actual behavior

The errors below can be logged and potentially crash a site. Unfortunately, there's not a known path of steps to reproduce this issue, even after inspecting the IIS log files.

This may be due to a standard bot attempting to index the site. No other logs occur when I'm able to find these exceptions.

If this is indeed related, the actual behavior includes crashing the application pool and causing a HTTP 503 error to be displayed.

Screenshots

None.
