How to add parameter name to error message in Postman test

I’m writing some tests in Postman. When writing the error message, I must input manually the name of the variable that is being tested. Is there a way to avoid having to put it by hand? In some tests, there are 200 variables.
If something like “pm.response.parameter” existed it would be of great help as you could write a generic error message and just have to paste it in all messages.

At the moment i am using something like:

pm.expect(value.proctrEs).to.eql(null,"error en proctrEs : "+pm.response.code);

But I was wondering if there is something like:

pm.expect(value.proctrEs).to.eql(null,"error en "+ pm.response.parameter + " " + pm.response.code);
