Passing a string with curly braces

Question

I'm using Artillery.io (v2.0.23) to make a POST call. And in my request body, I want to pass a string that contains double curly braces as follows:

json:
 text: "Hello {{ firstName }}"

But Artillery tries to interpret this as a variable called firstName and converts it to Hello undefined. To go around this, I've tried a bunch of things as follows

1. Hello {{`{{firstName}}`}}

2. Declare a new variable called

   variables:
    firstNameUnescaped: "{{firstName}}"
   json:
    text: "Hello {{ firstNameUnescaped }}"
   

3. Use a JS processor in the test YAML file

   beforeRequest: "sendCurlyBracedBody"
   

   And in the processor

   module.exports = {
    sendCurlyBracedBody: function (requestParams, context, ee, next) {
    requestParams.json = {
    text: "Hello {{firstName}}"
    }
    }
   }
   

None of the above three approaches helped. I see Artillery interpreting it as a variable and converting it to Hello undefined. How to pass that string without Artillery trying to read it as a variable?
