When you see the above error on a view criteria, you might be puzzled what went wrong with the condition. It is because, the searchable property of an attribute used on the filter condition is set is “no” which was earlier set to “yes”.
If you want to know what the filter condition is, just hover on the information icon to find the attribute name.
Revert the searchable property of the attribute to “yes” and publish your customization. Once done, open the “Edit Filter Criteria” on your view to see the filter condition appear now 🙂
Tip: If you have a requirement to make an attribute non-searchable, then find the dependencies especially those on view’s filter criteria and resolve it before you make them non-searchable.
