[NabeelTariq]

I generated a meeting using server-to-server oauth app and when I join the meeting with SDK it gives me an error

  generateSignature(

    sdkSecret,

    sessionName,

    role,

    sessionKey,

    userIdentity

  ) {

    const iat = Math.round((new Date().getTime() - 30000) / 1000);

    const exp = iat + 60 * 60 * 2;

    const oHeader = { alg: "HS256", typ: "JWS" };

    const oPayload = {

      app_key: "xZYFwOaR7C1vP76lewExQ",

      tpc: sessionName,

      role_type: role,

      meeting_number: this.meetingNumber,

      session_key: sessionKey,

      user_identity: userIdentity,

      iat: iat,

      exp: exp,

    };

    const sHeader = JSON.stringify(oHeader);

    const sPayload = JSON.stringify(oPayload);

    const signature = KJUR.jws.JWS.sign("HS256", sHeader, sPayload, sdkSecret);

    console.log("signature: ", signature );

    return signature;

  }

  async startVideoMeeting() {

    // Using "await" syntactical sugar:

    try {

      const data = await this.videoClient.join(

        "Cool Cars",

               this.generateSignature(

          "05IA7zFz26Rc0S01eGyoWAENKEVreXoN",

          "Cool Cars",

          1,

          "testmeet123",

          "Nabeel Tariq"

        ),

        "Nabeel Tariq",

        "testmeet123"

      );

      this.stream = this.videoClient.getMediaStream();

      // console.log(data);

    } catch (error) {

      console.log("Error: ", error);

      if (error.type == "JOIN_MEETING_FAILED") {

        console.log("join meeting failed. Reason: ", error.reason);

        console.log("error code: ", error.errorCode);

      }

    }
