arcpy.management.Project() thinks feature class is in feature dataset, won't run correctly.

Pro 2.9.5

Pretty much the label.

I'm trying to automate a process, using several tables and feature classes in memory (r'memory\exampleFC'). At the very end, I want to project one of these feature classes into a different coordinate system. (Edit for clarity: the destination for the results of Project() is a file geodatabase, not another in-memory table)

I keep getting the error 001489: Cannot project a feature class that participates in more advanced capabilities (such as topology and geometric network). The weird thing is I can use this in-memory table in the Project tool with the GUI, and it worked fine. However, even if I straight-up copied the Python command from it, I keep getting this error.

As suggested by the help doc, I've used CopyFeatures() instead. This works, but it is slowwwwwwwwwww. I'd like to use Project because I think it'll be faster and it's also more intuitive.

Why do I keep getting this error?

Edit: I realized an insert cursor, which I was already using the step before reprojecting, will reproject for me. But my question still stands.

The memory workspace is not supported as a location to write the output dataset.

I think the same applies to input as well.

The memory workspace is the input, the output is a file gdb

maybe that accounts for what you are seeing?

If you change your input to be from a geodatabase on disk rather than in memory workspace, does that work?

...It does. Weird.

Yet another thing today that isn't documented.

Sometimes this error can occur with a normal feature class in a geodatabase as well, and it is a Bug
