I'm getting this error when trying to mark a file as reviewed:
Marked file as viewed failed: TypeError: Cannot read properties of undefined (reading 'substring')

This is an azure devops PR not a GitHub PR. Clicking this:

• Extension version: 0.2.3
• Version: 1.97.1 (user setup)
• Node.js: 20.18.1
• OS: Windows_NT x64 10.0.22631

Steps to Reproduce:

1. Try to review an azure devops PR
2. Try to mark a file as reviewed
