We’re getting this error for a single client using our service. We’ve had our Square integration for about a year and this client has been using it about that long. It only happens with one of their locations.
The account/location work outside our integration.
One other note: I just spoke with the partner and they no longer thing the location is working from the Square Web Terminal. Maybe this is a more general issue with their account? I’ve recommended they reach out to support as well, but would still appreciate any available insight.
