AttributeError: module 'picologging' has no attribute 'PlaceHolder'

[cofin]

I'm using picologging on a project with uvicorn and I'm running into the following exception. Should this class exist in the picologging library? I can't find the actual implementation for this.

Here is the line referenced in the error:

picologging/src/picologging/config.py

Line 46 in 16f49d3

if not isinstance(logger, picologging.PlaceHolder):

and here is a chunk of the traceback:
