CORS error when sending requests from localhost:4200

I have Angular app that retrieves secrets from Doppler.

Regardless of which Bearer authentication type I use (ST or PAT), what resource I want to get, and what browser I use - it all fails because CORS error happens.

Screenshot cannot be uploaded, so look at it in OneDrive.

Thanks for further help!

UPD: I guess it is not a problem with Doppler service itself, but some problem with my machine. I tried another Key Management service, and it also fails with CORS.
UPD2: Despite that, even if I deploy the app to Heroku, the request to both yours and other service also failing with CORS. What is going on…
