Unsupported datatype when creating new Property via WbEditEntity API - pywikibot

26 Dec 2019


      Hi,  pywikibot experts:
I am now creating new Property using the wikidata Wbeditentity API
https://www.wikidata.org/w/api.php?action=help&modules=wbeditentity, I'm
running wikibase software via the wikibase-Docker images on my local
machine, and use the pywikibot() script:
data = {
    'datatype': 'math',  # mandatory
    'descriptions': {
        'en': {
            'language': 'en',
            'value': row['Property Description']
        }
    },
    'labels': {
        'en': {
            'language': 'en',
            'value': row['Property Label']
        }
    }
}
params = {
    'action': 'wbeditentity',
    'new': 'property',
    'data': json.dumps(data),
    'summary': 'bot adding in properties',
    'token': site.tokens['edit']
}
req = site._simple_request(**params)
results = req.submit()
It would report errors when creating the following datatypes:
*math wikibase-sense wikibase-lexeme musical-notation wikibase-form *
ERROR: P5973  param-illegal: A datatype was expected, but either missing or
not recognized. [messages:[{'name': 'wikibase-api-not-recognized-datatype',
'parameters': [], 'html': {'*': 'A datatype was expected, but either
missing or not recognized.'}}];     help:See http://localhost:8181/w/api.php
for API usage.
The other types will return success, just list some:
external-id
wikibase-item
...
geo-shape
However, the unsupported datatypes are in the supported datatype list by
the official document: https://www.wikidata.org/wiki/Help:Data_type
Any idea?
