POST submit error in Collection Test

[anikeit29 (Anikeit Bagaria)]

I am doing the Postman API Fundamentals Student Expert certification from Postman Academy
I am in the final step of Submitting my postman collection and followed exactly the instructions given in the course

But in the last stage I am getting an error which I can’t figure the meaning of.
What is the meaning of this error and how can I resolve this?

“errors”: [
{
“test”: “[COLLECTION] Collection level Auth is set to type API Key with header named api-key”,
“message”: “Cannot read properties of undefined (reading ‘type’)”
},
{
“test”: “4. [skillcheck] Set request auth to “API key” & header to “student-expert"”,
“message”: “Cannot read properties of undefined (reading ‘type’)”
}

The error is telling you what is wrong.

The API key should be set at the collection level. You appear to have it on the submit request.
