Getting Some syntax error (found \, expected identifier, string, number, bool at line 1, char 281)

SELECT percentile(“mean”::field, 85) as percentile_85 FROM “cymatics”.“one_year”./gsdfs.dagruntemp.durationtemp.success/ WHERE (“cluster”::tag =~ /^test$/) AND (“dag_id”::tag =~ /^test_$/) AND (“component”::tag = ‘’ + component + ‘’) AND time >= now() - 15m GROUP BY time(1m),dag_id::tag

if I remove component then it works perfect
