Oops! We were unable to save your document

Hello!
I’m having trouble saving changes on a page whenever I try to update it, I get this error.

I’ve tried with all three users on my repo, but it still doesn’t work.
I hope someone from the Prismic team can help me with this, please.

Update:
it’s only on this page and it’s only for uid changes and in the chrome console i have an error :
"error": "document_uid_conflict",
but i change an uid of the concerned page 20min ago

Hey @prismic38,

Have a look at this page: Error: This value is already used by another document , it should help you troubleshoot this. You might need to go find the original document causing the conflict. Let me know if it helps!
