Webservices data source multi-select parameter not working

[cbuffington]

I have a report that is hitting an api endpoint that consumes a multi-select parameter along with a few other parameters.  If i only choose one selection from the multi-select, the report loads with no issue.  When selecting more than one, the report throws the following:

 

Error Message

null

The control is using java.util.List  as its type and the server already handles parsing the format.  The report dies before it sends out the api request.  Anyone have a remedy for this issue?
