I suppose the two things may be related. 1. Popups in statements are not displaying (with message "There was an issue dispalying this preview") 2. I cannot get any results from Query Service, even for simple queries.
ad.1) There are only a few items in the database: https://indxr.wikibase.cloud/wiki/Item:Q2 https://indxr.wikibase.cloud/wiki/Item:Q3 https://indxr.wikibase.cloud/wiki/Item:Q4 There are no popups in any of them. Browsers javascript console says: "warnings": { "extracts": { "warnings": "Item:Q5 has content model wikibase-item, which is not supported; returning an empty extract." } },
ad.2) Even simple query: https://indxr.wikibase.cloud/query/#SELECT%20DISTINCT%20%3Fitem%20%3FitemLab... or https://indxr.wikibase.cloud/query/#SELECT%20%3Fitem%20%3FitemLabel%20WHERE%...
returns "no matching record founds".
How can I diagnose further what could be the problem? Could it be a problem with the updater? How can I check it?

- Popups in statements are not displaying (with message "There was an issue dispalying this preview")
I reported this issue when the platform was WBStack: https://github.com/wbstack/mediawiki/issues/68 It appears to remain an issue. The underlying task to support extracts in Wikibase is owned by Wikidata with low priority and has not been materially updated since September 2018: https://phabricator.wikimedia.org/T199096
It may be appropriate to refile this on Phabricator under Wikibase.cloud to disable Popups linking to that issue. Although really I think WMDE product should be going through all the issues on the WBStack account as most remain as issues.

You have not specified your prefixes. wd: is Wikidata; that default is maintained even though autosuggest suggests that it will use local data items. Which was another bug reported on WBStack: https://github.com/wbstack/queryservice-ui/issues/4
You can override them with the following: PREFIX wd: https://indxr.wikibase.cloud/entity/ PREFIX wdt: https://indxr.wikibase.cloud/prop/direct/
But personally I would suggest using your own custom prefixes to make crystal clear that you are not using Wikidata, e.g. https://furry.wikibase.cloud/wiki/Project:SPARQL/examples#Conventions
