Question

I've tried to run from this project, but got some obstacles:

running with npm

1. Regarding usage service, you I succeeded only when I ran
   npm install openapi-types eslint-plugin-flowtype eslint-plugin-jsx-a11y eslint-plugin-react eslint-plugin-react-hooks
   and not
   npm install
2. I've edited the config\default.json file to use available port

"server": {
    "port": "8083"
  },

then using Swagger API ( /) sent :

curl -X 'POST' \
  'http://localhost:8083/layer' \
  -H 'accept: */*' \
  -H 'Content-Type: application/json' \
  -d '{
  "cacheType": "file",
  "name": "my_layer_name",
  "tilesPath": "/home/alexbel/MapProxy/tiles/",
  "maxZoomLevel": 18
}'

but got the following response:

{
  "message": "Internal Server Error"
}

the printed log was:

No configuration was provided, adding default console logger.

What is missing ? My guess that I have to point to mapproxy.yaml somehow, but I didn't find or missed it in the documentation.

running with docker

I have used following command:
docker run --name mapproxy-api --rm -it -e SERVER_PORT=8083 mapproxy-api:latest

however the http://localhost:8083/docs/api/ returns me 404 error code

$ docker logs mapproxy-api

Start with config/default.json, the npm installation instructions, and the Docker startup command, then reproduce the POST /layer request and the /docs/api/ request described here. Trace the logged ENOENT error and the Docker 404 using the existing API and container documentation. Done means the required setup and configuration are identified and both reported behaviors have a documented or verified resolution.
