Hide Prefix doesn't work in Qlik Sense 3.2 SR4

[rajat2392]

My application was working fine.

I wanted to hide current selection for a particular field from users.

I have used "hide prefix" in the application script but I am getting below errors as in image.

Is this is a bug in the 3.2 SR4 version?

Please help if someone has faced the same and knows the solution.

Thanks
