Potential AttributeError if raw_msg attribute exists but is None. The getattr function only returns the default value when the attribute doesn't exist, not when it exists with a None value. If pe.raw_msg is None, line 3632 will call None.endswith() and crash.

Fix:

msg = getattr(pe, "raw_msg", None) or pe.msg
if msg.endswith("does not exist"):

Or add a null check:

msg = getattr(pe, "raw_msg", pe.msg)
if msg and msg.endswith("does not exist"):
Suggested change
msg = getattr(pe, "raw_msg", pe.msg)
if msg.endswith("does not exist"):
msg = getattr(pe, "raw_msg", None) or pe.msg
if msg.endswith("does not exist"):
