An issue occurred while evaluating the Pre-request Script: Unable to access the 'get' property of an undefined object

I need help accessing the response of my POST request in Postman using a Pre-request Script.

Script below :

var mobiles = postman.environment.get("mobiles");

if (!mobiles)
  {
    mobiles =["8824444866","8058506668"];  
  }

var currentMobile = mobiles.shift();
postman.environement.set("mobile","currentMobile");
postman.environement.set("mobiles",mobiles);

When I try to send the request, an error pops up in Postman with the following message:

There was an error in evaluating the Pre-request Script: Cannot read property 'get' of undefined.

I'm looking for any suggestions or solutions to resolve this issue. Thanks!

Answer №1

If you were searching for it, the code 

postman.setEnvironmentVariable(key, value)
can now be replaced with the new one pm.environment.set(key, value), which is just a shorthand version of the same feature.

The API access to the environment is through pm, not postman. Additionally, there seems to be a typo in your script – it should be environment, but you have written environement.

Here's the corrected script:

NOTE: This will only work on the native app

var mobiles = pm.environment.get("mobiles");

if (!mobiles)
  {
    mobiles =["8824444866","8058506668"];  
  }

var currentMobile = mobiles.shift();
pm.environment.set("mobile", currentMobile);
pm.environment.set("mobiles", mobiles);

If you prefer using the postman.* API instead, here's the script for that:

For Chrome App & Native App (Legacy Support)

var mobiles = postman.getEnvironmentVariable("mobiles");

if (!mobiles)
  {
    mobiles =["8824444866","8058506668"];  
  }

var currentMobile = mobiles.shift();
postman.setEnvironmentVariable("mobile", currentMobile);
postman.setEnvironmentVariable("mobiles", mobiles);
