Original GitHub issue: https://github.com/hoppscotch/hoppscotch/issues/3675

Originally assigned to: @jamesgeorge007 on GitHub.

Is there an existing issue for this?

I have searched the existing issues

Current behavior

When I use a variable inside the request body I get the following error:

  PARSING_ERROR Unable to parse -
  {"url": "http://<<testapihost>>:8081"}
   (ENV_EXPAND_LOOP)
  REQUEST_ERROR Invalid URL

my env.json is

{
  "name": "test-variables",
  "variables": [
    {
      "key": "testapihost",
      "value": "localhost"
    }
  ]
}

the part where the collection has the variable:

"body": {
                        "contentType": "application/json",
                        "body": "{\"url\": \"http://<<testapihost>>:8081\"}"
                    },

Steps to reproduce

1- create an env variable
2- create a request
3- add this env variable into the body
4- run hopp test -e env.json collection.json

Environment

Production

Version

Local

Hi, please share a sample collection and environment (if different from above) export that can be used to reproduce the issue.

The problem I have is to use variables for the url to send and also put those variables inside the body. the following example shows the error:

bug/echo/should return 200 reported errors:
  PARSING_ERROR Unable to parse -
  {
   "first_name": "<<first-name>>" 
  ,"last-name": "<<lastname>>" 
  } (ENV_EXPAND_LOOP)

a simplified version of the collection:

{
    "v": 1,
    "name": "bug",
    "folders": [
        {
            "v": 1,
            "name": "echo",
            "folders": [],
            "requests": [               
                {
                    "v": "1",
                    "name": "should return 200",

                        "contentType": "application/json",
                        "body": "{\n \"first_name\": \"<<first-name>>\" \n,\"last-name\": \"<<lastname>>\" \n}"

        }],

Thanks for the sample exports. I reproduced the issue and have raised a fix.

This happened since the single environment export format only considered the first variable entry and the resolution step failed to find a match for other entries ending up in the ENV_EXPAND_LOOP state.
