Getting HTTP 500 / fatal: expected 'packfile' error

Environment

  • Surface: Web and Windows client
  • Browser or app version: Agent says to tell you “the failing request is a cloud-to-cloud Git download”
  • Affected feature and model, if relevant: Sites on Work

Bug

My website project is worked on completely in the cloud environment (so Sites?).

My long github push failed (I think) and then I got this error: HTTP 500 / fatal: expected ‘packfile’.

I can’t continue working on my site.

I have used the Support chat bot and escalated to a support specialist.

Reproduction

Steps or a minimal example prompt:

Can you try again?

Retried with fresh credentials. The source download still fails with HTTP 500 / fatal: expected ‘packfile’.

No deployed files, existing work or GitHub branches were changed. The Support request remains the safest next step.

Can you try again now?

Retried now with fresh credentials and a shallow download of main. It still fails with HTTP 500 / fatal: expected ‘packfile’.

The deployed Site, existing files and GitHub remain unchanged. Support escalation is still needed.

Diagnostics

Exact error or screenshot: HTTP 500 / fatal: expected ‘packfile’.
When it happened (with timezone) and how often: 1:39 AM PST 10/28/26. Continues failing on reattempts

If there is someone from support viewing this, please help me. Case 18495977

I’m not able to work on my project while this is happening.
