How to hide or change error notification?

Bad argument to +
the operation + cannot accept the argument [0], empty string, …

So when i get this error in the application is there a way to change the message to something else?

Why don’t you find the error instead

There are a set of text boxes. As i noticed, If any of the text boxes are left empty then this error pops up. I wanted it to change this error text to something simple.

then you need to place a method for checking if textbox is empty then dont do +.
