[Bug]: Pivotal Tracker Importer fails if user created Custom Fields exist

[st-kep]

Do I have the most recent api-cookbook code?

• I am using the latest code available on the main branch of the api-cookbook repo.

Is there an existing issue for this?

• I have searched the existing issues.

Current Behavior

If you create a Custom Field in the Shortcut GUI, then attempt to import a Pivotal Tracker the import fails with the following error message. ({Path} replaces real path)

Traceback (most recent call last):
  File "/{Path}/api-cookbook/pivotal-import/initialize.py", line 587, in <module>
    sys.exit(main(sys.argv))
  File "/{Path}/api-cookbook/pivotal-import/initialize.py", line 572, in main
    cfg = load_config()
  File "/{Path}/api-cookbook/pivotal-import/lib.py", line 448, in load_config
    return validate_config(populate_config())
  File "/{Path}/api-cookbook/pivotal-import/lib.py", line 344, in populate_config
    priority_custom_field_id = default_priority_custom_field_id()
  File "/{Path}/api-cookbook/pivotal-import/lib.py", line 289, in default_priority_custom_field_id
    if custom_field["canonical_name"] == "priority" and custom_field["enabled"]:
KeyError: 'canonical_name'
make: *** [Makefile:19: initialize] Error 1

Dumping the custom_field variable shows that for user created Custom Field, the "canonical_name" field does not exist.

Expected Behavior

The Pivitol Tracker importer is able to import Pivitol Tracker exports after a Shortcut Custom Field is created.

Minimal Reproducible Example

• Manually create a Custom Field in Shortcut
• Execute the importer initialization of the Pivotal Tracker importer.

Environment

• Operating system: Ubuntu/Windows
• Python/JavaScript version: Python 3.10

Further Information

The workaround to continue evaluating the imported that I used was to move the custom_field["enabled"] check before the custom_field["canonical_name"] == "priority" check and disable the custom fields I created in the GUI. Then I was able to execute the import.
