-dump-config flag does not work with Docker image

[michael-pxr]

Describe the bug When I use the -dump-config flag to create a config.json file using the Docker image, I get an error open config.json: no such file or directory.

To Reproduce

docker run --rm webpsh/webp-server-go:0.9.10 webp-server -dump-config

Expected behavior I expect it to print a JSON object like

{
  "HOST": "127.0.0.1",
  "PORT": "3333",
  "QUALITY": "80",
  "IMG_PATH": "/path/to/pics",
  "EXHAUST_PATH": "./exhaust",
  "ALLOWED_TYPES": ["jpg","png","jpeg","bmp","gif","svg"],
  "ENABLE_AVIF": false,
  "ENABLE_EXTRA_PARAMS": false
}

Screenshots and logs Instead I get the following logs
