I'm trying to add a new field to the "information" panel of a review request. The error I'm getting during initialization is "fieldset is not None", even though I put 'info'. Furthermore, when I tried to debug this with unit tests I get an error that settings_local can't be defined, but the docs seem to claim I should be getting that file built for me by the tool. I'll put the class, and full error below, hopefully they are legible.

A slightly redacted class:

class CLField(BaseEditableField):
field_id = 'vendor_cl'
label = 'Vendor CL'

class VendorIntegrationExtension(Extension):
metadata = {
'Name': _('Vendor Integration'),
'Summary': _('foo'),
}

def initialize(self):
ReviewRequestFieldsHook(self, 'info', [CLField])

The error from the logs:
