It would be good to handle this error. Workaround when being flooded with it is to turn valuetool off and then on again:

Hi, I removed (commented) line 511 of 'valuetoolwidiget.py' file to force reload layer list when close/open projects to prevent this error. Please update the plugin to version 3.0.3 Tell me if the error persists! Thank you for help.

Sorry, not fixed. It occurs if using "selected layers" in valuetool when the layer is removed from the project. I think it requires a try/except.

I gived up and followed your advice! I used a "try except" block. Let me know if version 3.0.4 is ok. Thanks!

AlisterH commented 4 years ago

Yes, fixed.
