column "{colId}" holds value {value} which is not in its lookup options. Showing the raw value; set `lookup.unknownLabel` or `lookup.allowCustom` to change that.

What happened

A row holds a lookup id that the option list does not contain, so there is no label for it and the raw id is shown. It is not reported while the options are still loading - ids that are about to resolve are not a fault - and not at all when allowCustom is set, because then a value outside the list is expected.

The fix

Add the value to the options, set lookup.unknownLabel to control what an unmatched value shows, or set lookup.allowCustom if values outside the list are legitimate.
