Struggling with authentication issue on the 3rd HTTP request

[itwaman]

Hi everyone
it's now 48 hours that I'm fighting with this error and I'm out of ideas
The final goal is to export the list of Intune devices (and possibly other reports) every day (this logic is already working perfectly using a PowerShell script, but I want to move it to Logic App and release the server from some load.
As you can see from the pictures, the first 2 HTTP requests (1st is POST, 2nd is GET) are working perfectly.
But in the GET request at the bottom of the flow, I'm getting an error about authentication, even if I'm using the same method (tenant ID + Client ID + Secret): this last GET is supposed to download a 25MB zip file.

Any idea on how to fix this? thanks!

Authentication information is not given in the correct format. Check the value of Authorization header.
