Describe the Bug

(I am omitting irrelevant configuration lines below)

This configuration worked in 1.19:

libraries:
  Movies:
    operations:
      metadata_backup:
        add_blank_entries: false

This now causes a crash:

Traceback (most recent call last):
  File "/modules/config.py", line 872, in __init__
    default_path = input_dict["path"]
                   ~~~~~~~~~~^^^^^^^^
  File "/usr/local/lib/python3.11/site-packages/ruamel/yaml/comments.py", line 851, in __getitem__
    return ordereddict.__getitem__(self, key)
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
KeyError: 'path'

To fix I had to update my config:

libraries:
  Movies:
    operations:
      metadata_backup:
        add_blank_entries: false
        path: config/Movies_Metadata_Backup.yml
