Heyy all, I am really stuck at this point. After completing all tasks, when I am sending a request for testing my collection, then it shows -
Set env variable from script and set next request | AssertionError: expected [] to have a length above 0 but got 0
I’ve updated the collection link, saved each request after every change I made but the same error.
Please help me out
Hi, are you using the student expert collection? You’re going to want to go back over the second folder on scripting and collection runs. 
Yes, I am using the student expert collection. I have done all the tasks that were in scripting and collection runs. 
Hey, I’ve checked all the steps of the folder Scripting and Collection runs, but again same error.
Make sure you have saved all of your requests and updated the link through the share button!
Yes ma’am done that, at first I thought it was because of outdated postman tool but then I performed it on updated version and later performed it on postman for web too. That test is failing every time.
Can you share your collection link here?
OK so you’ve missed a step in the second folder, if you open the second request Get specific player and uncheck the parameter so that you see the first set of instructions that should walk you through–you need to add a script to the Get all players request that sets an environment variable.
Heyy thankyou so much 
finally it worked.
