API call in custom connector returns empty array

[BertMuller1968]

I defined a custom connector in Power Apps and added an API action. I provide an URL and parameters. Power Apps transforms this URL by adding the "europe-002.azure-apim.net/apim" part.

My request becomes:

And this is the response, an empty array:

This is not correct, there should be items in the array.

When I paste the exact same URL in Postman, using the same token, and send the request, I get the correct answer:

Other API calls work fine from the Custom Connector test environment, it's just this one that acts strangely. And it's not just the test environment, in my canvas app the operation gives me empty arrays where I expect an array filled with items.

What am I doing wrong here?

Solved, after re-publishing the app.
