Here’s a further reduced query that results in the same error:
SELECT ?aLabel ?bLabel WHERE { { SELECT (wd:Q1 AS ?a) ?aLabel {} } SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". } }Removing ?a or ?aLabel from the subquery, or removing the binding from ?a (SELECT ?a … without any AS), all remove the error.
