M-Files Web Type Error:Cannot read properties of undefined (reading '56302b2f-4dad-4220-a910-251f9c94d2fe')

There are some functional differences between how MDCC (metadata card configuration) works between clients; could it be that you're using a feature that's not supported in the Classic Web?

Details are here: M-Files Web

Thanks Mr Crag for answering my question. First of all, we did not get such an error before. We've been getting this error for a while. I don't think it's possible that mfiles doesn't support dynamic value definition. But if we're getting this error because of another change we made, I couldn't find that unsupported feature. 

" reading '56302b2f-4dad-4220-a910-251f9c94d2fe' "  feature is a feature that we have defined in the autofills section in the configurations. In other words, it means that it does not read the automatic dynamic values ​​defined outside of this.

Without digging into this specifically I'm not sure.  You could start by disabling some of the MDCC rules so that you can identify which one is causing this, then cross-reference the document above to double-check that it's supported.

If you feel there's been a regression (i.e. something worked previously but now does not), or you feel that there's a bug, or that the documentation is not complete, please do reach out to support@m-files.com.   They will also need things like M-Files version number.

I have no idea what MDCC rules are. Could you expand a little more, please?

My apologies - "MDCC" means "metadata card configuration": Metadata Card Configuration (m-files.com)

It's not important. Thanks for answering my questions.
