CORS blocking API calls

[blazing haven]

My Angular Project can not get any Data from my API (a NestJS Backend where CORS should be enabled). I tryed doin a Proxy.config.json file and adding it to the angular.json but it did not work like all other approches i tryed. My frontend and Backend are served in a Docker Container and you can see my source code here (newest branch selected): https://github.com/FreakeyPlays/vs-lab/tree/feature-13

My Console Output:

And the Headers of a Request:

[visual sleet]

Read the error message, the problem is not about cors. You are providing a string, not a URL. The message explains the expected formats

[blazing haven]

No it still is cors i jsut tryed different url to connect to my container

[visual sleet]

With which url?

[blazing haven]

i mean i can try it aigan but evrytime it showed this error

one second

[visual sleet]

It's detected as a cors issue as you are trying to access another domain. But that's about the url format here, not the origin itself

[blazing haven]

oh okay

i will try it with http://localhost:5000 i just need to build real quick

[visual sleet]

Not 500 but 5000 based on previous screenshot

[blazing haven]

now i get this

[visual sleet]

Are you sure it's on port 5000?

[blazing haven]

i get a bit confused with the ports while using Docker. Inside my docker i have the port 5000 and when i run my docker compose i map the outsoide Port of 8081 to 5000

do i need to use the 8081

i thought because i have them connected via a bridge that i need to use the inside ports

oh man... i think i needed to use the Outsideport

im so sorry this was a stupid help post

i should have found this out
