V0 stopped connecting to Cosmos DB in project previews

About two days ago when developing applications required to query Cosmos DB everything worked fine in preview and production, but since yesterday the preview just shows “[v0] Error loading data: Failed to fetch data” in the debug logs when trying to query Cosmos DB via SDK.

What could have happened?

Do you have a chat link you can share with us?

Some other debugging ideas:

  1. Compare your preview environment variables with production
  2. Check the Vercel function logs for more detailed error messages

Yes, I have a chat link - may share in a secure message. How can I access Vercel function logs? Environment variables have the same value.
