@murungatim this JWT is not properly formed.

It is missing the appKey and tokenExp

The exp needs to be minimally 30 mins from the IAT

@murungatim your appKey / sdkKey are empty. You need to put in your clientID as your appKey / sdkKey

@murungatim ,

Now the appKey and sdkKey are missing from the key value pair.  
IAT and Expiry timeframe is also too close to each other, it needs to be 30 mins apart minimally

@murungatim what error are you getting now?

For starters, try to change the role to 0 and make sure you join a meeting which is internal / the same as the SDK account

```auto
ZoomMtg.init({
  leaveUrl: leaveUrl, // https://example.com/thanks-for-joining
  success: (success) => {
    ZoomMtg.join({
      sdkKey: sdkKey,
      signature: signature, // role in SDK signature needs to be 1
      meetingNumber: meetingNumber,
      passWord: passWord,
      userName: userName,
      zak: zakToken, // the host's ZAK token
      success: (success) => {
        console.log(success)
      },
      error: (error) => {
        console.log(error)
      }
    })
  },
  error: (error) => {

@murungatim could you try without ZAK token, and try to join a meeting with role : 0 ?
