Seeing an error message in logs from the Lutron Telnet app:
java.lang.NullPointerException: Cannot invoke method parse() on null object on line 80 (method parse)
Often appears in logs right after a dimmer has activated, i.e.:
rcvd: OUTPUT,40,1,0.00
Any ideas on how to resolve this?

I still seem to be seeing this error, any thoughts on how to resolve this?
What troubleshooting steps have you already taken to date?
Did this only appear after a recent change to the Lutron integration?
Did you add or remove any devices on the Hubitat or Lutron side?
Help us help you by providing as much information as possible.
The basics are always good
What model Hubitat Hub?
What version of Hubitat software is running on your HE hub?
Have you tried rebooting your Lutron SmartBridge Pro?
Have you tried rebooting your HE hub?
Have you tried rebooting your HE hub with the 'Show Advanced Options' and 'Rebuild Database on Reboot' both checked?
Can you reproduce the problem at will? This would be very helpful if you can identify what sequence of events triggers this error message.
Just a few ideas to help get a baseline.
