All API endpoints give NULL pointer access error

[milesoberstadt]

I installed your plugin with WebTools, and I see it register as Cast in the Plugins list. However, clicking on any of the buttons results in the error "This plugin is not responding.". After testing the API endpoints, I can hit the root endpoing (http://localhost:32400/chromecast?X-Plex-Token=XXXXXXXXXX), but all other routes ( http://localhost:32400/chromecast/devices?X-Plex-Token=XXXXXXXXXX ) give the following error:

<Response code="2000" status="ValueError: NULL pointer access">

</Response>

I've never written a Plex plugin, so I don't really know how else to help. Please let me know if any other info is needed to diagnose this.

Did you ever figure this out? I have the same issue :(

[michaelarnauts]

Nope. I've given up on Phlex for now.

[aniljbhatia]

I managed to get it working by making a change to one of the library files - it wasn't error checking properly. I posted details on a different issue: https://github.com/d8ahazard/Cast.bundle/issues/16

[d8ahazard]

Please check out https://github.com/FlexTV.bundle for the latest iteration of the plugin.

Also, there's an experimental stand-alone app for homes without a PMS server, but you want to control cast devices at https://github.com/d8ahazard/FlexConnect - and docker - https://github.com/d8ahazard/docker-FlexConnect

If you have issues, feel free to report them there!
