Getting authorization error on Halfway Test

Iā€™m running the Halfway Test and all the tests pass except one. The error message is

[COLLECTION] Collection level Auth is set to type API Key with header named api-key | AssertionError: expected undefined not to be undefined

Here is the authorization tab from the collection:

Iā€™ve tried adding the postmanrulz api-key on both the main collection and the test collection, as well as the No Auth, to no avail. Should I recreate the collection once again or is there a fix that I havenā€™t been able to find?

How are you setting the authorization when you add the api-key?

ā€œNo Authā€ will be incorrect.

What does the instructions tell you to do? (Can you link to the training docs you are using).

Hi Mike, Iā€™m setting the authorization by clicking on the collection and clicking on the authorization tab.

No Auth was what was selected when I created the Postman collection. I only tried changing it because of the failed test.

Iā€™m using the online tutorial.

Which online tutorial, can you please post the link, and then show a screenshot of where you have currently set the authorization. (On the request or collection)
