Hi @ik-nz ,

I checked the HTTP 500 issue on /.netlify/functions/gather-feedback. The problem was caused by insufficient permissions on the Sanity token that the function was using. After updating the function to use a valid token with “create” permission for the production dataset, feedback submissions are now successfully stored.

I ran the function locally with my own Sanity token (SANITY_TOKEN) and verified that:

• The function returns a 200 status on submission.
• Submitted feedback documents are visible in the Sanity Studio under _type: "docsFeedback" in the production dataset.
• I could fetch all existing feedback using client.fetch('*[_type == "docsFeedback"]'), confirming that new entries are properly stored.

So the issue should now be resolved — the function can create feedback documents without errors.

Still occurs in prod.

Are you having the access to production databases and keys by any chance? if so , use a "developer" sanity key token for the .env SANITY_TOKEN.
Refer to this below:

[ik-nz]

I have no such access. This issue is a bug report about the configuration of the live production website.
