All integrations were made following the Zoom Video SDK documentation.  
I’m having some unsolved issues in the documentation.

When I have a subsession created and I try to create another, the second one is not created because the following error is returned:  
Uncaught (in promise) TypeError: e.map is not a function

The function I use to create the subsessions is this:

```auto
export const createSubsessions = async (subsessionClient, subsessionNames = [], autoAssignType = 1) => {
    if (!subsessionClient) return
    await subsessionClient.createSubsessions(subsessionNames, autoAssignType)
}

```

In the subsessionClient parameter I pass the subsession client, in the subsessionNames parameter I pass an array containing strings with the room names.  
Ex:  
`createSubsessions(client.getSubsessionClient(), ['Room 2'], 2)`

Below is more information about the versions and system I am using:  
Video SDK version: 1.12.5  
React version: 18  
Next JS version: 14.2.2  
OS: Windows 11  
Browser: Google Chrome  
Browser Version 129.0.6668.70 (Official Build) (64 bits)

I discovered what was causing the error.  
When subsessions are open in the session, no other can be created, so whenever I open a subsession to include a participant in it, I must close it immediately afterwards if I want to create a new subsession.  
I did not find an explicit explanation for this rule in the documentation.
