Swagger not working (cors) in demo deploy

[SebastianThorn]

Hi,

The swagger container can not access the openapi.json-file due to cors

I'm using the standard docker-compose.yaml and docker compose up

Error message from Swagger:

Errors

Fetch error
Failed to fetch http://localhost:8080/api/openapi.json
Fetch error
Possible cross-origin (CORS) issue? The URL origin (http://localhost:8080) does not match the page (http://localhost:8081). Check the server returns the correct 'Access-Control-Allow-*' headers.

Request with curl:
