Author-login empty on commit messages for Azure backend

[techbecca]

Describe the bug
I've set up commit messages templates according to the documentation (see CMS config-file). I expected to see the users login email or username when using {{author-login}}, but the value just returns empty. The users are logged in to the same organization as the repository is in. I can see errors in the console log related to decap's calls to fetch Azure users.

backend:
  name: azure
  repo: [redacted]
  tenant_id: [redacted]
  app_id: [redacted]
  branch: main # Branch to update (optional; defaults to master)
  commit_messages:
    create: Create {{collection}} “{{slug}}” by "{{author-login}}"
    update: Update {{collection}} “{{slug}}” by "{{author-login}}"
    delete: Delete {{collection}} “{{slug}}” by "{{author-login}}"
    uploadMedia: Upload “{{path}}” by "{{author-login}}"
    deleteMedia: Delete “{{path}}” by "{{author-login}}"

To Reproduce

1. Go to the config.yml file for Decap
2. Set commit message templates which includes the {{author-login}} variable
3. Commit and build (so the templates will be used)
4. Create a new post from the Decap CMS UI
5. See commit message

Expected behavior
The commit messages should include the author's username or email, as well as the collection and slug for the new item created.

Actual behavior
Only the collection and slug for the item created is included in the commit message, not the author details.
