InternalError: too much recursion

I recently upgraded from dhtmlxgrid v.3.5 to version 5.2.0.
Initially, I was getting “too much recursion” for a specific location in the code, and I then stopped including connector.js.
That eliminated getting the error for that location in the code.
However, now I am getting a new “too much recursion” for a different location in the code.
I have tried not including dhtmlxdataprocessor.js, but that has not made a difference.
What do I need to do?

Could you please, provide a complete demo or a demo link, where the problem can be reconstructed locally.
Here you can find a tutorial about creating a complete demo:
