Well, I would say it’s not really a bug, more an unfortunate combination of features. There are currently two ways to get an entity ID out of MWAPI: Given a “client-like” API result like this <page _idx="32882493" pageid="32882493" ns="0" title="Mary E. Cobb" contentmodel="wikitext" pagelanguage="en" pagelanguagehtmlcode="en" pagelanguagedir="ltr" touched="2021-06-28T08:26:03Z" lastrevid="1030833675" length="7412"> <pageprops defaultsort="Cobb, Mary E." page_image_free="Mary_E._Cobb.jpg" wikibase_item="Q6779361" /> </page> then the MWAPI config ?item wikibase:apiOutputItem mwapi:item. corresponds to the XPath `pageprops/@wikibase_item`, i.e. the `wikibase_item` attribute of the `pageprops` child element of that `page` element. Given a “repo-like” API result like this <page _idx="102358522" pageid="102358522" ns="0" title="Q107110037" contentmodel="wikibase-item" pagelanguage="en" pagelanguagehtmlcode="en" pagelanguagedir="ltr" touched="2021-06-08T03:16:28Z" lastrevid="1437430459" length="1963"> <pageprops wb-claims="3" wb-identifiers="0" wb-sitelinks="1" /> </page> then the MWAPI config ?item wikibase:apiOutputItem mwapi:title. corresponds to the XPath `@title`, i.e. the `title` attribute of that `page` element. In both cases, the assumption is that the XPath selects the entity ID as a string, but for the `title` attribute, that’s only true for items, not other entity types. (On Wikibase installations where items aren’t in the main namespace, I assume it’s not even true for items.) But I’m not sure what the best way to solve this would be – I would be hesitant to hard-code something like “remove everything up to the first colon” into MWAPI. Maybe we can add a new value for the `query+prop` API parameter, which would add the page’s entity ID (as an attribute on the `page` element, like the `contentmodel`, `pagelanguage`, etc.)? And then we could add that by default to the MWAPI “Generator” service, and add a new shortcut, `mwapi:entityid` = `@wikibase_entity` or something like that.
