Just searching your error message in the forum is showing other people having same issue.

The issue is related to a wrongly created channel link.
If you use text base configuration review your items file, a : is most likely missing.

If you use UI based condition you would need to review the JSON DB.

If you can upgrade to OH3.4 there is a fix that will show you in the log which item is affected

Thanks, but how do I install 3.4?
I selected “main” branch in openhabian -config (my understanding is that by selecting the main as the branch it will install the latest release). I am still on 3.3

 You are currently using the "main" openHABian environment version.                     │

The openHABian version to contain the very latest code for openHAB 3 is called "main". │
This is providing you with the latest (openHAB3!) features but less people have tested │
it so it is a little more likely that you run into errors.

Version 3.3 is the current main/stable

3.4 is still in development and you would need to select a different branch.

Do a copy of your entire system before and only upgrade the copy before you break something else

Thanks,

I have seen the upgrade to the latest milestone is under 41 in de config tool

Kind regards
