netcam_url_invalid error

[Dweller]

I've attempting to configure motion to use a remote camera which is actually a raspberry pi running mjpeg_streamer which works fine with homebridge and zoneminder..

I've a netcam_url of http://zion.local:8080?action=stream

And the error I'm getting from motion are:-

[ERR] [NET] netcam_url_invalid: Invalid URL. Can not parse values.

Am I missing something obvious?

Thanks in advance.

It appears the URL parser likes a / at the end of the host:port part..
