Error on Embedded dashboard with boolean category parameter


I am using Embedded dashboard on my application, my dashboard has parameters, one is a category that is connected to a field in the table that has boolean value, that parameter give me this error

ERROR: operator does not exist: boolean = character varying\n Hint: No operator matches the given name and argument type(s). You might need to add explicit type casts

I have also attached screenshot of my dashboard

Thank you
