Ucpnode_err.log Error: Cannot find module 'ini'

FreePBX 13.0.192.19
Asterisk Version: 11.21.2
User Control Panel: 13.0.42.3

I can login to User Control Panel and select any option without any error
But /var/log/asterisk/ucpnode_err.log keeps growing in size.
I’m getting the following error repeatedly

2017-11-24 01:15 -08:00: Error: Cannot find module 'ini’

How do I fix this error and as a temporary solution can I simply delete ucpnode_err.log to recover disk space?

Thanks

I was able to fixed the issue by reinstalling UCP Node Server
The /var/log/asterisk/ucpnode_err.log is now approx 15.8 GB.
Can I simply delete this file?
Do I need to shut down “fwconsole stop” before deleting it?

Thanks
