Custom Field 'checked' changed to "checkbox' and this affects post_args because the post arg has remained unchanged

[xu2xulim]

There is some inconsistency found in set_custom_fields for what used to be type = 'checked'

if custom_field.field_type in ['text', 'number', 'date', 'checked']:
            if value == "":
                post_args = {'value': ""}
            else:
                post_args = {'value': {str(custom_field.field_type): value}}

The Trello api documentation is as follows

The type of Custom Field to create.

Valid values: checkbox, list, number, text, date

But when updating a CF it is still using {'checked' : value}...below is copied from the example from Trello API document

{
  "value": {
    "text": "<string>",
    "checked": true,
    "date": "2018-03-13T16:00:00.000Z",
    "number": 2154
  }
}

Above seems to be validate during my test.
I changed
if custom_field.field_type in ['text', 'number', 'date', 'checked']:
to
if custom_field.field_type in ['text', 'number', 'date', '**checkbox**]:

and hardcoded this
post_args = {'value': {str(custom_field.field_type): value}}
as
post_args = {'value': 'checked' : value}}

and my code was able to execute
