Hi folks, hoping you can help. I'm running through the Wikidata tutorials, and I'm getting an error thrown up while following the Inverse listeria tutorial, hoping that someone can help.
When I do the schema, I get the following error:
"Wikimedia import URL (P4656) statements with invalid format.
Values for this property are expected to match the regular expression (?:https?://)(?:www.)?((?, which is not the case for https://en.wikipedia.org/w/index.php?title=List_of_metro_systems&oldid=1184716036 added on Caracas Metro (Q1363954)."
As well as:
"Unit missing for patronage (P3872) Values such as 358000000 on Caracas Metro (Q1363954) are expected to have units."
I'm not particularly familiar with regular expressions, but after asking a friend who knows more than me it appears that perhaps it might be something to do with the regular expression. (On the second error, as far as I can see, "units" is optional, but it's still throwing up the error.)
Additionally, and I don't know if it's related, but the code block around the regex in the screengrab below extends to the end of the line, rather than to the end of the regex:
Any ideas or advice welcome!
