For example this CLI command will throw an exception is rich isn't installed, although it works fine otherwise:

kasa --host 192.168.1.168 --username xxx --password xxx feature check_latest_firmware
Discovering device 192.168.1.168 for 10 seconds
Executing action check_latest_firmware
Raised error: expected string or bytes-like object, got 'UpdateInfo'
Run with --debug enabled to see stacktrace

the reason for this error reported by --debug:

[...]
Raised error: expected string or bytes-like object, got 'UpdateInfo'
Traceback (most recent call last):

TypeError: expected string or bytes-like object, got 'UpdateInfo'

The regex substitution used in this replacement for richs print() function only works for strings.

More complex objects need to be preprocessed by repr() in advance.

   This seems to work for me, with & without rich (14.2.0) using python 3.12:

   

   Which versions are you using?

   This seems to work for me, with & without rich (14.2.0) using python 3.12.

   Could you please execute this little script (test.py), which should demonstrate the actual cause of this issue:

   import re
   
   class TestObj:
       member_num = 12
       member_str = "xxx"
   
   to = TestObj()
   
   re.sub(r'[x]', '', to)

   The output will look very similar to this:
