Hi, I’m having problems sending my first message, when I want to create a new open channel I get the following network error:

Hi @Gladys_Felix,

Welcome to the Sendbird Community!

I apologize for the delay in our response. Can you provide the following information?

1. SDK Version
2. Confirmation that you can successfully call `connect()` without issue.
3. Network results when request is made by SDK.

Hi! @Tyler I am using Sendbird Chat SDK for JavaScript V3. I have no problem starting a connection, it correctly creates the user but using only the line of code to open a channel shows me the error

```auto
sb.OpenChannel.createChannel(function(openChannel, error) {
    if (error) {
        // Handle error.
    }
})

```

I also use javascript SDK V4 and I get the following error

```auto
TypeError: _openChannel.OpenChannelCreateParams is not a constructor

```

P.S: I’m implementing the SDK Javascript in Vuejs 2
