I am trying to construct a Web API that queries a data entity and compares a field in that data entity with an array of values that I've stored in a local variable (created from another a!queryEntity). I've hardcoded the value in my first query so I know what results I should get in the second one. Both queries work individually, but I get this expression evaluation error when I combine them. Any suggestions on what I'm missing? I'm pretty sure that once I get this working, I'll also have to add something to account for null values in the first query....but that's another issue. See the attached file for the code.

Expression evaluation error at function a!queryEntity [line 33]: Cannot apply operator [IN] to field [checkid] when comparing to value [TypedValue[it=197,v={TypedValue[it=1,v=621],TypedValue[it=1,v=622],TypedValue[it=1,v=623]}]].

@judym Try casting the local!checkIds to a desired data type. For instance, if checkId is of type Number Integer, configure the checkId query filter value as tointeger(local!checkIds).

The issue I could see as of now and as per my experience is, type of local!checkIds is resolving to Any Type and this could be confirmed by making a quick test with typeof() and typename() functions.

Let's see if any other practitioners could make valuable suggestions.
