Hmm.. I did some playing around and found what might be the problem. Does the client ID you're using have the correct authorization scopes? For channel.subscription.gift, you need the channel:read:subscriptions scope. If you are unsure how to give yourself that scope, you can check out my comment in #13 here to get it set up.

As a personal note: filed #58 to improve error messaging here

BUT evnets sub works correctly I recieve all the event i subscribed

When you say this, do you mean that you're still receiving the events properly? Are you using the Twitch CLI to test this?

[TiotBenjy]

Yes I receive event properly because when I use rewards the event is correctly triggered and message is sent in the chat. Today I'm resub on the channel and the event works perfectly.

I don't use Twitch CLI.

I don't understand this error ^^

[mitchwadair]

I see, okay. So the other thing that may be happening is that you already had a subscription made with that condition. If you call

tes.getSubscription("channel.subscription.gift", { broadcaster_user_id: <your-id> }).then(console.log);

You'll probably see that you've already made that subscription and that is why your events are functioning properly. When an existing subscription is present Twitch returns a 409 response when attempting to subscribe to it again. #58 should also help with identifying this case

[mitchwadair]

Just released v0.7.1 that should provide better output for you

[TiotBenjy]

Okay I will update the module and test it.

Thanks !

[TiotBenjy]

Yes that's the problem !

Thank you for your help and your reactivity !
