Changedetection API requests returning "null"

[xNS5]

Changedection version: 0.44
Host: Docker compose file on an Alpine Linux VM

I'm trying to get the contents of a specific watch via http://<url>:5000/api/v1/watch/<uuid>/history/<snapshot> and the response returns null. Upon further testing, the following routes also return null:

• /api/v1/systeminfo
• /api/v1/watch -- both GET and POST
• /api/v1/watch/<uuid> -- GET (haven't tried PUT)
• /api/v1/watch/<uuid>/history/<timestamp>

All of the HTTP requests I make returns with a 200, but the content is null.

Edit: This behavior is also present when running cURL.

Maybe this is just due to confusion on my end for the purpose of the API, but my assumption is that if I were to run a GET request for a specific uuid and timestamp I'd get the contents of the diff for that specific snapshot. Is that assumption incorrect?

Final edit: The root cause of this was that I disabled the API access token. I'm only serving this on my local network, so I didn't think it would be necessary to require it. Turns out if the token is disabled, any HTTP request (sans .../history for some reason) will return null. Might be something to fix at some point.
