check mutation status with the requestId

Why it happens

Coda API docs gap: write endpoints (insert, update, upsert, delete rows) do not apply edits synchronously. They return HTTP 202, meaning the edit was accepted and queued, and it can take a few seconds to apply or may fail if invalid.

Edge cases

• If your error message differs even slightly, this is probably a different issue; search the exact text.
• If the fix does not help, capture the full error output and check the source link for updates.

Coda API docs gap: write endpoints (insert, update, upsert, delete rows) do not apply edits synchronously. They return HTTP 202, meaning the edit was accepted and queued, and it can take a few seconds to apply or may fail if invalid. Resolved: Do not treat a 202 as "done". Every write response includes a requestId; pass it to the getMutationStatus endpoint to find out whether the edit was actually applied. Also note reads come from the most recent doc snapshot and can lag a few seconds behind the browser; if you need a guaranteed-fresh read, send the X-Coda-Doc-Version: latest header and handle the 400 the API returns when its view is stale.
