How to use multi-value dashboard variable in query parameter

[mbtx2]

Hello,

I have a jsonata backend Infinity query. The API I am querying has a query string parameter that allows for selecting what particular elements you are interested in. I have a dropdown dashboard variable that allows for multiple values. In JSONApi plugin, this would automatically be passed to the query parameter as a semicolon-delimited list for the list of whatever items are selected for that variable. With Infinity, if more than one item is selected, Infinity fails with this (from query inspector):

A:0 rows
This feature is not available for this type of query yet

Is there a way to do this with backend query?

Thank you

I determined that the behavior is due to something else.
