Has something changed in the last few years? I get an error running this.

>>> renderData[c4d.RDATA_PATH] = r"MyPicturePath.exr"
TypeError: GeListNode_ass_subscript expected Description identifier, not str
The above exception was the direct cause of the following exception:
SystemError: _PyEval_EvalFrameDefault returned a result with an error set

c4d.RDATA_PATH evaluates to a string, but its looking for the type Description identifier

Now in 2022 I'm getting an error using SetFilename(). It expects an int where c4d.RDATA_PATH evaluates to the string 'from_code_filename'. I'm new to C4D..has the c4d constants been changed from ints to strings?

Example:

>>> doc.GetActiveRenderData().GetData().SetFilename(c4d.RDATA_PATH, str("my_filename"))
Traceback (most recent call last):
  File "console", line 1, in <module>
TypeError: an integer is required (got type str)
