SYNC211: Record invalid field
What this means
Your store refused a value it was sent.
The store's reason names the value. Correct it where you entered it, then save again. Usually the value belongs to a record — a product, customer or order — but this code can also come from a settings or sign-in request the store refused; then correct it on that screen.
Your data
Don't clear this device's data — it may hold changes your store doesn't have yet. A refused edit to an existing product, variation, customer or coupon is usually undone automatically and logged as SYNC202 instead. If it shows as this code and the change is listed in Store health → Database, the automatic undo didn't happen — treat it like any other listed change. A settings or sign-in request leaves nothing to save.
Troubleshoot
- Expand the log entry and read the store's reason and the endpoint: the reason names the value, and the endpoint shows whether it came from a record or from a settings or sign-in request.
- Correct the value where you entered it — common causes are a value out of range, a rejected format or a required option left empty — then save again. If the change is not listed in Store health → Database, the store's version was restored, so make the change again with the corrected value. If it is still listed under "… changes never reached your server" in Store health → Database after you correct it, tap Send again on its row.
- If the record is instead listed under "… changes were held" with "Your store required a current version", no value is at fault — decide between Send again and Discard device change as described in SYNC221.
- If it was a settings or sign-in request, correct the value on the screen where you entered it and save again. Site admin: the browser's developer tools (Network tab) — or Advanced → Toggle Developer Tools in the desktop app — show the store's response when the details are not in the POS log.
- Site admin: if a named value looks correct in the POS, compare it with the same record in WP Admin — plugin-added validation on the store can reject values the POS considers fine.
