Hello,

I have a super urgent matter of node-red crashing upon opening. It has been operating completely fine up until about 1 hour ago where now it crashes repeatedly. Below is the error I get. Running on a Raspberry-Pi and my node-red says v1.3.4 from the dropdown menu in the top right.

```auto

First off, you should be able to start it from the command line using the `--safe` option.

Second, what changed? It shouldn't just start crashing.

What is the full command using the --safe?

Also, quite literally nothing changed. While remotely monitoring it I noticed our node-red-contrib-opcua nodes were not connecting and it was stuck in a loop of auto-restarts.

On Pi Node-RED works better with the Firefox or Chrome browser
 
Use node-red-stop to stop Node-RED
Use node-red-start to start Node-RED again
Use node-red-log to view the recent log output
Use sudo systemctl enable nodered.service to autostart Node-RED at every boot
Use sudo systemctl disable nodered.service to disable autostart on boot

Apparently there is a bug in the ubidots node that crashes node red when it gets invalid data.

To run node red in safe mode, which runs the editor but does not start the flows, use `node-red --safe`

I ran in safe mode and disabled some nodes one by one. Started with the node-red-contrib-opcua nodes because they have historically given us a problem but no change. The Ubidots Out node (which publishes to Ubidots) is fine, but the Ubidots In node (which pulls data from Ubidots) causes node-red to crash immediately. I have reached out to them about this. Thanks for your help guys.
