[Bug] Pi-hole API Response Contains Invalid JSON

Pi-hole API Response Contains Invalid JSON

When fetching DNS stats at Glance from the Pi-hole API at https://url/api.php?summaryRaw&topItems&overTimeData10mins&auth=token, the response contains invalid JSON with the error "invalid character '<' looking for beginning of value".

Expected Behavior

The Glance should return a valid graph response with the requested DNS statistics.

Actual Behavior

The API returns an HTML response instead of JSON, causing the error "invalid character '<' looking for beginning of value" when parsing the response.

Steps to Reproduce

1. Set the Pi-hole API URL and token in the Glance application configuration:

   - type: dns-stats
   service: pihole
   url: https://pihole.domain.eu/
   token: YOUR_TOKEN

2. Run the Glance application to fetch the DNS stats.

Environment

• Glance version: 0.6.0
• Pi-hole version: 5.18.3

Additional Information

• The Pi-hole API endpoint is accessible and returns a valid JSON response when tested directly.

• The Glance application is configured to use the correct URL and token.

Please let me know if you need any other information to investigate this issue.

Thanks for reporting this!

I can't seem to replicate the issue on my end while using the same version of Pi-hole. Do you have a way of checking the full HTML response? I'm wondering if it's a 404 or something else.

This might have something to do with the lack or addition of /admin/ in the path. For me, this URL works:

https://url/admin/api.php?...

And this does not:

https://url/api.php?...

You should only specify the domain in the config, as I believe you already have.

OK, nvm, i found that i had in traefik configured middlewares to replace the admin and prefix to get a shorter URL. Everything works like a charm, thank you and sorry for bothering! :D
