LogicApp liquid transform using minus operator

Question

I have a Liquid transform JSON-JSON. I have the following:

{
   "totalCount": {{15 | minus:1 }} 
}

But i'm getting

 "totalCount": 15

and not

"totalCount": 14

What am i doing wrong here?

Answer 1

Found the problem. It should be uppercase "M" in minus

{
   "totalCount": {{15 | Minus:1 }} 
}
