Hey @descent-module-ast11

Welcome to the Postman Community! :postman:

This scope of variable doesn’t store anything outside of the execution of that request. That’s the reason why you wouldn’t see anything when using pm.variables.get() in the second request.

You would need to change the scope to something else (Global/Collection/Environment) that would store the value and make it reusable.

When debugging, ensure that you’re making use of the Postman Console. This will show you exactly what’s the value of something is at any given time.

console.log(pm.variables.get('createdBy'));
