Error "Unexpectedly found a non-primitive value for field type button."

This message means miniExtensions encountered a button value in a context that expected a primitive value. It does not by itself establish that the button is broken in Airtable. Check that the button’s URL works in Airtable, refresh the base schema in miniExtensions, and retry. If it persists, contact support with the extension and affected field so we can investigate the value-conversion path.
