[Bug - Partner Center] Something went wrong correlationId

Describe the bug
The Overview page for one specific Edge Add-ons extension in Partner Center fails to load and shows "Something went wrong" with a correlationId. Other products load normally. This extension is published and also has an existing draft submission. This error has been showing up for multiple days and I can't get access to my extension at all.

Backend API calls for draft-related endpoints return 404 NotFound, which appears to break the Overview page.

To Reproduce
Steps to reproduce the behavior:

1. Go to https://partner.microsoft.com
2. Navigate to Dashboard > Products
3. Click on the extension with product ID eafe8b27-507e-4ba3-97f5-138826465e95
4. The Overview page fails with "Something went wrong"

DevTools Network shows the following endpoints returning 404:

/overview/submissiondetails/draftsubmission
/submissionvalidity
/submissionvalidity/draftsubmission/Publish/isAllowed

Expected behavior
The Overview page should load normally and display the extension’s published and draft state without errors.

Screenshots
Screenshot of the "Something went wrong" page and DevTools Network tab showing 404 responses for draftsubmission endpoints.

Desktop
OS: Linux (x86_64)

Version: Latest stable versions
Reproduces in Incognito / clean profile

Additional context
Only this product is affected; other extensions load normally.
The extension is published and has a draft submission.

Example failing API responses:

CorrelationId: 70237f13-6870-453f-acb8-11b4ca5f13f5
Time (UTC): 19 Feb 2026 05:05:30

CorrelationId: dd03c348-9c13-4ddb-ba21-f66e3e4a0303
Time (UTC): 19 Feb 2026 05:05:47

This appears to be a corrupted or orphaned draft submission record causing the Overview page to fail when loading draft state.
