Hi, SupportTeam!

First of all, I hope you will all recover from the devastating loss and pain brought on by the earthquake. I also hope you and your loved ones are OK. I am so very sorry.

I have a project inside an ABP Framework solution which is an API client to access an external API. From the get go, any test did with Postman is working correctly.

Structure:

Module file:

Extension file:

The rest are related to the API itself - models, client, etc.

The services are properly initialized. I can inject them with no problem in any page on the frontend.

But I always get the same error:

The server doesn't have CORS policies, and any test with something different than ABP works.

What am I doing wrong? Any tips would be appreciated.

Thanks,
Catalin
