Opening list form error

Hello guys. I have a small problem and I can't seem to figure out what's the source of it. In the attached picture you'll see the error I receive. This happens when I try to open a form ( ListForm ) on the web. If I run the app from the designer I don't receive any error, but when I try to use that specific from the Web I receive that message.
Can someone please help me with any ideas/suggestions?
Thank you very much,
Lucian.

Lucian,

thanks for reporting the issue. It does not look like a known one and requires investigation.

Can you please provide more info? Your platform version and a demo infobase (or a data processor) that can generate this error.

This happened when I upgraded my 1C platform from 8.2.19 to 8.3.7. Now, the thing is that I receive this error when I open the ListForm form the WebClient, not from the ThinClient. From the ThinClient I don t receive this error, it works great, but when I try this from WebClient it all goes downhill..
Any ideas on how to solve this problem ?

strange thing - looks like compatibility issue between 1c and web-server

Lucian, can you please provide a demo configuration that has this error? You can attach it to a forum post.

Hello. Sorry for the late response. It seemed to be a compatibility problem and I solved it.
Thank you for your reply.
Lucian
