I deployed a flow to my node-red on the raspberry pi 3 and after that it keep restarting giving the following error:

I searched the net. It seems that I created a flow with a node that is not fuly configured so I had to remove this flow. I was able to make node-red start again by renaming the flow file.

go to the folder 

pi@raspberrypi:~ $cd /home/pi/.node-red/
pi@raspberrypi:~/.node-red $ ls -la
total 56
drwxr-xr-x  4 pi pi  4096 Jun 22 17:20 .
drwxr-xr-x 26 pi pi  4096 Jun 22 17:37 ..
-rw-r--r--  1 pi pi 13283 Jun 21 18:03 .config.json
-rw-r--r--  1 pi pi   100 Jun 22 16:46 flows_raspberrypi_cred.json
-rw-r--r--  1 pi pi  3560 Jun 22 17:20 flows_raspberrypi.json
-rw-r--r--  1 pi pi  3119 Jun 22 16:46 .flows_raspberrypi.json.backup
drwxr-xr-x  3 pi pi  4096 Apr 10 12:20 lib
drwxr-xr-x  4 pi pi  4096 Jun 21 17:59 node_modules
-rw-r--r--  1 pi pi  9064 Jun 21 17:45 settings.js

I renamed the one with flows_raspberrypi.json and then started node-red and it works this time.
