TASK DESCRIPTION
I am running this code:
import pywikibot
site = pywikibot.Site("wikidata", "wikidata")
repo = site.data_repository()
item_id = "Q64835" # Özcan Arkoç
item = pywikibot.ItemPage(repo, item_id)
if item.exists():
print(f"{item_id} exists")
else:
print(f"{item_id} doesn't exist")
It crashes on `item.exists()`:
Traceback (most recent call last):
File "/home/amir/devel/pywikibot-core/pywikibot/tools/__init__.py", line
771, in wrapper
return getattr(obj, cache_name)
^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'Claim' object has no attribute '_type'. Did you mean:
'type'?
During handling of the above exception, another exception occurred:

raise KeyError(f'{prop} does not exist')
KeyError: "Claim(DataSite('wikidata', 'wikidata'), 'P6615') does not exist"
CRITICAL: Exiting due to uncaught exception KeyError:
"Claim(DataSite('wikidata', 'wikidata'), 'P6615') does not exist"
The same code outputs "Q64834 exists", "Q64836 exists", and "Q7 doesn't
exist" when running with these Q numbers, but Q64835
<https://www.wikidata.org/wiki/Q64835> causes it to crash.
Maybe it happens because property 6615
<https://www.wikidata.org/wiki/Property:P6615>, which was used in a statement
on that item, was deleted a couple of months ago. The statement was deleted,
too
<https://www.wikidata.org/w/index.php?title=Q64835&diff=prev&oldid=2190834717>,
and it's not even the latest edit on the item. In any case, such a thing
probably shouldn't cause the whole script to crash.
