RangeError: Maximum call stack size exceeded

This is my code:

componentWillUnmount() {
    console.log("willUnmount");
    const { typememberid } = this.state;
    this.chabok = new chabokpush(authConfig, options);
    console.log(typememberid, authConfig.username, options.realtime);
    console.log(Base64.decode(this.props.user.phone));
    this.chabok
      .getUserId()
      .then(userId => {
        if (userId) {
          this.chabok.register(userId);
          console.log("already registered", userId);
        } else {
          console.log("name: ", name);
          this.chabok
            .register(Base64.decode(this.props.user.phone))
            .then(({ deviceId }) => {
              console.log("Registered", deviceId);
              console.log("TypememberID: ", typememberid);
            })
            .catch(error => {
              console.log("Failed to register", error);
            });
        }
      })
      .catch(error => {
        console.log("Fail to get user ID", error);
      });
    this.chabok
      .getUserId()
      .then(res => {
        console.log(res);
      })
      .catch(err => {
        console.log("failed sub: ", err);
      });
    this.chabok.subscribe(`private/${typememberid}`);  ////////////////this is where i subscribe on channel
    this.chabok.on("message", msg => {
      console.log(msg.content);
      PushNotification.localNotification({
        message: msg.content
      });
    });
  }
