Looking for some help to resolve what should be a simple Filter Array expression.
I have a Variable Array which has a list of "Id" and "CardNo"
The Inputs to the Filter Array expression

The CardNo value is being looked up from the Apply to Each function - I want to use this CardNo to filter the array.

But no matter what I try, the output is always []

Even wrapping the filter in quotes gives the same output

Or using a string expression

Any ideas?
