API Error: Unexpected token 'I', "Internal S"... is not valid JSON

[thisguyshouldworkforus]

Description

I'm not sure what I'm doing wrong, hoping someone can clue me in, but my implementation of the Pi-Hole widget is not working. All I get is an API Error.

I am able to connect to the URL from the homepage server, and I have many other widgets operating normally. I am also able to successfully get valid JSON when I visit the URL directly http://pihole.myinternal.domain.com/admin/api.php

    }
}

This is the section of my services.yaml file:

    - PiHole:

        href: http://pihole.myinternal.domain.com/admin/login.php

          url: pihole.myinternal.domain.com

I'm also able to query the endpoint from the homepage server as well:

curl "http://pihole.myinternal.domain.com/admin/api.php?summaryraw&auth=0123456789abcdef0123456789abcdef0123456789abcdef0123456789abcdef"

This, to me, seems to suggest something wrong with either Homepage, or the widget.

Where's the bot when you need it. The widget isnt broken, there are similar issues if you search. Try curl from inside the container, not the server.

[thisguyshouldworkforus]

It succeeds:

/app # curl "http://pihole.myinternal.domain.com/admin/api.php?summaryraw&auth=0123456789abcdef0123456789abcdef0123456789abcdef0123456789abcdef"
