Run the following test case in sharded_collections_jscore_passthrough suite const coll = assertDropAndRecreateCollection(db, jsTestName()); const viewName = "identityView" ; assertDropCollection(db, viewName); assert.commandWorked(db.createView(viewName, coll.getName(), [])); const secondaryColl = assertDropAndRecreateCollection(db, "secondary" ); const secondaryViewName = "secondaryIdentityView" ; assertDropCollection(db, secondaryViewName); assert.commandWorked(db.createView(secondaryViewName, secondaryColl.getName(), [])); // Works just fine. jsTestLog(coll.aggregate([         {$match: {a: 1, b: 5}},         {$unionWith: {coll: secondaryViewName, pipeline: [{$match: {a: 1, b: 5}}]}}     ] ).toArray()); // Fails to resolve the view. jsTestLog(coll.explain().aggregate([ {$match: {a: 1, b: 5}}, {$unionWith: {coll: secondaryViewName, pipeline: [{$match: {a: 1, b: 5}}]}} ] ));
