Hello there, I want to deploy growthbook in docker, but I have an error in GUI "Unexpected token '<', "<!DOCTYPE "... is not valid JSON" I took a standart docker-compose.yml and change only that
environment:
- APP_ORIGIN=172.17.0.1:3000
- API_HOST=172.17.0.1:3100
- JWT_SECRET=1234566
- ENCRYPTION_KEY=4daHS2zS5cJGAtl2
- NODE_ENV=dev
this ip is default ip of docker0 interface. Api page opens on that api and port.

can you access the API directly?
it should load a json file with some config info if it works
you can also check the docker container logs for more information - its likely that the API request that is expecting a JSON object is failing because the API is returning an error

You'll either see the error when you visit the API url directly, or you'll see the error log from docker
