I usually have seen that Error when I had a BPM and I removed it but somehow the files stuck around.
You can try running Directive Update via System Management / Business Process Management there should be a button / tab that has “Directive Recompile” and you can check both outdated / up-to-date. It will rebuild BPMs and clear left-overs.
The other time I have seen it is when I added a new Extended UD Column and I did not do Schema Update.
