**Description**  
I have a custom zoom call integration in swift. I’m trying to join a session by calling `joinSession()` the returned value is always `nil`. Neither `ZoomVideoSDKDelegate`’s callback - `onSessionJoin()` nor `onError` is getting invoked.

Not sure what is going wrong here.

**Which iOS Video SDK version?**  
v1.11.10

**To Reproduce(If applicable)**  
Steps to reproduce the behavior:

1. Go to ‘Download Video SDK for iOS v1.11.10’
2. Setup the SDK in your app
3. Initialize the SDK
4. Join session:

```auto
  let sessionContext = ZoomVideoSDKSessionContext()
    sessionContext.token = token
    sessionContext.sessionName = name
    sessionContext.userName = userName
    let session = ZoomVideoSDK.shareInstance()?.joinSession(sessionContext)
    if session != nil {
      print("Joined seession")
    } else {
      print("Error in joining session")
    }
.
.
.
  func onSessionJoin() {
    print("onSession join triggered")
  }

```

**Smartphone (please complete the following information):**

- Device: iPhone 14
- OS: iOS 17.2

**Additional context**  
This is my payload to generate the JWT token:

```auto
{
  "app_key": "#####",
  "tpc": "GUbQCnJUBm9PsCnpzZej_TIAGO_1718730335",
  "role_type": 0,
  "version": 1,
  "iat": 1718825106,
  "exp": 1718832306,
  "user_identity": "member#9390e7ec9114e13656104ffb7435bcf9_TiagoCouto"
}

```
