I'm trying to use a query-typed dashboard variable, for which the datasource plugin has a custom formatting function. Unfortunately, the formatting function attempts to find the name of the field the variable is for (in order to be able to construct a query of the form field:value1 OR field:value2 ...), and in doing so, it runs into a runtime error, because it attempts to lookup a field on the variable which is undefined.

Screenshot of the variable definition:
