How to pass boolean values using Postman?

Help Hub
6

Hi there,

I’m trying to randomize a true/false boolean value, which I want to assign to a variable that I can then pass to my Body and post as part of my JSON. I tried this:

var arrayCert = [true, false];
pm.globals.set('certVal',  arrayCert[Math.floor(Math.random()*arrayCert.length)]);

Which does get me a random variable in certVal . But when I try to pass that variable in my Body like so:

"Certified": "{{certVal}}",

I get this message:

"INVALID_REQUEST_PARAMETER: 'Certified' Expected type boolean but found type string; ",

I think the double quotes in the body is passing the variable as a string, hence the error. If I change it to:

"Certified": true,

Then the post works as expected. Is there anyway I can pass a random boolean in this way?

Thanks so much for any help.
