Error log - 'NoneType' object has no attribute 'loop'

Mycodo Mycodo Issue/Bug
1

My controller is not operating as I expected it would.

After restarting the daemon server and checking the daemon logs, there appears to be an error, but I am unsure what has caused it and how to fix it (searched for the error message and also checked my inputs, outputs & functions)?

Can someone explain if this is a major issue?

Are you running the latest version?

3

Yes. This is the message on the upgrade screen:

No upgrade is available. You are running the latest release, version 8.12.6
4

Do you have empty elements on the function page?

5

No. I have double checked them. All are assigned and activated.

6

Try deleting the spacers and adding them again.

7

I deleted the spacers for the functions. The error still occurred.

I then deleted all the spacers for the inputs and outputs. The error still occurred.

I then deleted all the inputs, all the outputs and all the functions. The error was resolved.

I added back all the spacers, all the inputs, all the outputs and all the functions. The error did not occur.

Problem solved.
