Yup. It's because you're getting rate limited from the Gateway, so it sends a Payload with an error message. Will have to handle this and apply some sort of rate limit.

I hope this problem will be solved quickly and API will grow a lot.

[stuyy]

Yep, since the API allows 120 requests per 60 seconds, that means you can only send 2 events per second. So I might just add a setTimeout(). However, I may set up a PriorityQueue structure and use that to handle events to prevent rate limiting. Will have to experiment. Thank you for bringing this up.

[dongsu8142]

I want you to fix the error quickly.

Stuff like this takes time, give the man a break

[dongsu8142]

okay I'm sorry I rushed you.
