Does the grid work? If both is true, I suggest to either ignore it, or open a support case to make Appian aware of this minor issue.</p><div style="clear:both;"></div>https://community.appian.com/thread/154154?ContentTypeID=1Tue, 07 Apr 2026 05:29:31 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:44ccbe02-48fd-4185-8870-2317891d784dShubham Aware<p>Wrap relationship field references in if(isnull(...), &quot;&quot;, ...) or use a custom record field with null-safe expressions instead of referencing relationship fields directly in grid columns.<br />After any Record Type schema change, verify all grid column fieldConfigs still point to valid fields.<br /><br />Also you can try debug,&nbsp;<br />Temporarily remove grid columns one by one and reload - when the error stops, the last removed column is the culprit.</p><div style="clear:both;"></div>
