Invalid Signature Error with Zoom Meeting SDK (3.6.1)

Meeting SDK
1

Dear Zoom Support Team,

I am currently integrating the Zoom Meeting SDK into our web application, but I am encountering an “Invalid signature” error when attempting to join a meeting. Despite following the documentation and testing with the sample web SDK, the issue still exists.

Hi Hamza,
Have a look at the Troubleshootng guide for the meeting sdk signature validation

@hamzasuleman Hope you will be fine.

Here is NodeJS sample

function generateSignature(meetingNumber, role) {
    const iat = Math.round(new Date().getTime() / 1000) - 30;
    const exp = iat + 60 * 60 * 2

    const oHeader = {
        alg: 'HS256',
        typ: 'JWT'
    }

    const oPayload = {
        sdkKey: process.env.ZOOM_APP_KEY,
        mn: meetingNumber,
        role: role,
        iat: iat,
        exp: exp,
        appKey: process.env.ZOOM_APP_KEY,
        tokenExp: iat + 60 * 60 * 2
    }

    const sHeader = JSON.stringify(oHeader)
    const sPayload = JSON.stringify(oPayload)
    const signature = KJUR.jws.JWS.sign('HS256', sHeader, sPayload, process.env.ZOOM_APP_SECRET)

    return signature;
}

And here is valid payload params

{
  "sdkKey": "ajQ8mmtQ_GKxIzGCg4XSA",
  "mn": 87954282182,
  "role": 1,
  "iat": 1714569281,
  "exp": 1714576481,
  "appKey": "ajQ8mmtQ_GKxIzGCg4XSA",
  "tokenExp": 1714576481
}

Thanks
