TASK DESCRIPTION

When editing query like this:

SELECT ?item ?title WHERE {
  SERVICE wikibase:mwapi {
    bd:serviceParam wikibase:endpoint "ru.wikipedia.org" .
    bd:serviceParam wikibase:api "Generator" .
    bd:serviceParam mwapi:generator "search" .
    bd:serviceParam mwapi:gsrsearch "intitle:/Дом[-]музей [БК]о/" .
    bd:serviceParam mwapi:gsrlimit "max" .
    ?item wikibase:apiOutputItem mwapi:item .
    ?title wikibase:apiOutput mwapi:title
  }
}

I get these errors in console:

wdqs.min.93ef020….js:1 Error: Unknown prefix: mwapi
    at Object.performAction (vendor.min.418c896….js:1)
    at z.parse (vendor.min.418c896….js:1)
    at z.Parser.n.parse (vendor.min.418c896….js:1)
    at i.parse (wdqs.min.93ef020….js:1)
    at e.setQuery (wdqs.min.93ef020….js:1)
    at e._drawQueryHelper (wdqs.min.93ef020….js:1)
    at o (vendor.min.418c896….js:1)
e._drawQueryHelper	@	wdqs.min.93ef020….js:1

Two issues here:


mwapi: is a standard prefix, so it shouldn't be "unknown"
Even if it were unknown, this should not produce JS errors
