Check package throws error on standard find query


I have added the check package.
Ever since many subscriptions are throwing errors on harmless queries.

For example:

Notifications.find({userId: this.userId}, { sort: { date: -1 }, limit: 30 });


Exception from sub noti id j8gzqRRW254bczaPZ Error: Match error: Failed Match.OneOf or Match.Optional validation

Sanitized and reported to the client as: Match failed [400]

Any idea what can be the problem?

EDIT: I’ve found out that removing the search options make the find query work. But why? This works: return Notifications.find({userId: this.userId});

I’ve got this error today every time I tried to use limit in query options at server-side. I’m using webpack:webpack and after some hours of investigation, I found that removing babel polifill solves this issue for me.

Hope this helps.
