method not found

[alext0408]

So, I've been fixing Dynamo project, that was written for Revit and bumped onto such function __TryGetValuesFromNestedDictionaries(). Only because of this I get a warning, that ruins the whole program, you can see the warning below
Translation: Warning: method "__TryGetValuesFromNestedDictionaries()" not found So the question is where to take this function(what extra library or something do I need) or how to fix this issue?

The image shows content based on a 'nodes to code' operation. So your best option would be to recreate it based on what it does rather than trying to find something that may no longer exist. It doesn't appear to be that complicated to recreate it from the node names etc.

It is hard to say what the missing function is doing. For some reason transaction is required but no changes appear to be made unless the missing function is making them?

Apart from that you should ask on Latest Revit topics - Dynamo (dynamobim.com)
