Expected Behavior

  1. Body with the string array variable is rendered correctly and the value is a string array, as in the envrionment
  2. Request is sent and returns 200, body was read correctly

Actual Behavior

  1. Body parameter that contained the string array variable, it is sent as a complete string, without []," or white spaces.
  2. Request fails this due to bad value sent because of body render

Reproduction Steps

  1. Create a variable in env, any env type, that is an array json
  2. Add the array json in a body, as whole, not just 1 element of it
  3. (optional) do a console log in the scripts to see the variable in console for comparison purposes
  4. Check console for the curl send of the body
