Unable to start event listner (Error: You should create pull-point subscription first!) #21

Hi,

Since today I'am having trouble to start a listner. I can communicate with the device. The device (reolink410) is capable of handling pullpoints (getCapabilities). Furthermore, the setup was working earlier. At this moment node-red will stop and restart after trying to start the listner. The log revealed the following stack trace;

Error: You should create pull-point subscription first! at Cam.pullMessages (/root/.node-red/node_modules/onvif/lib/events.js:188:10) at Cam._eventPull (/root/.node-red/node_modules/onvif/lib/events.js:309:9) at Cam.

I would be happy to get any hint towards a resolution. Thanks in advance,

After doing half a day of debuging I ended up in creating two issues. One here and one on the ONVIF library page. As a final resort I just reboted the camera and 'magically' everything started working again.
