Hello,
I have a Debian VM with Docker installed. I have several containers including Metabase and NGINX as a reverse proxy. My “global” NGINX configuration nginx.conf makes static files available, including my GeoJSON static files :
events {
worker_connections 1024;
}
worker_processes auto;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
tcp_nopush on;
keepalive_timeout 65;
gzip on;
include /etc/nginx/conf.d/*.conf;
}
For each container, I have a configuration file which is included in the global configuration file. To make the static files available, I've configured them as follows:
server {
listen 80;
server_name static.jb.fr;
location /geojson/ {
alias /etc/nginx/html/static/geojson/;
add_header Content-Type application/json;
}
}
My containers are all on the same network, so they can communicate with each other. From the Metabase container, if I do a curl, I get a 200 response code:
docker exec -it metabase-metabase-1 curl -I http://static.jb.fr/geojson/departements.json
HTTP/1.1 200 OK
Server: nginx/1.27.4
Date: Wed, 19 Mar 2025 12:56:23 GMT
Content-Type: application/json
Content-Length: 1079714
Last-Modified: Wed, 19 Mar 2025 12:54:54 GMT
Connection: keep-alive
ETag: "67dabe9e-1079a2"
Content-Type: application/json
Accept-Ranges: bytes
But when I want to add the map to the Metabase web interface, specifying the same URL, the API returns a response code 400 and specifies the message The GeoJSON URL returned an invalid content type. I've tried setting the Content-Type header to application/geo+json, then application/json, but to no avail as the error persists. It's as if the API can't contact this URL, whereas in the same container, the curl call returns a code of 200.
My file complies with defined rules:
- 1MB sized
- Uses geographic coordinates
What can I do / What's wrong? Thanks for your help!
