Only one device is receiving the notification

[fjerbi]

I'm having a weird behavior in my APP while working on a push notification functionality that sends notifications to a team when a camping is created.

I console logged, and notifications were sent to all team, but only the camping creator receives the notification.

I'm running two emulators, I tried the same thing using messaging in the Firebase console, and only one emulator device receives the notification.

Did anyone faced similar situation?

const postSubmit = async () => {
    const userIds = team;
    const campData = {
      meetingPoint,
      description: `You've been invited to a camping at ${selectedCamping?.name}`,
      startingDate,
      endingDate,
    };
  
    if (selectedCamping && selectedCamping._id) {
      setCamping(selectedCamping._id.toString());
    } else {
      console.error('Selected camping is invalid:', selectedCamping);
      return;
    }
  
    setLoading(true);
  
  await  axios
      .post(`API`, {
        sender: user.user.id,
        team: userIds,
        objects,
        camping,
        meetingPoint,
        description: `You've been invited to a camping at ${selectedCamping?.name}. Click here to view details.`,
        users: userIds,
        startingDate: selectedDates.start,
        endingDate: selectedDates.end,
        notes,
      })
      .then(async function (response) {
        console.log(camping);
        SuccessAdventureCreation(selectedCamping?.name);
  
        // After successful adventure creation, send notifications
        for (const userId of userIds) {
          try {
            // Assuming each user has an associated FCM token
            const token = await getTokenForUser(userId); // function to get the user's FCM token
  
            const notificationData = {
              "message": {
                "token": token,
                "notification": {
                  "title": "New Invitation",
                  "body": `You've been invited Check it out!`,
                },
                "data": {
                  "campId": `${response.data.campId}`, // Assuming the response contains an campId
                },
              },
            };
  
            await axios.post(
              `https://fcm.googleapis.com/v1/projects/app-id/messages:send`,
              notificationData,
              {

                  "Authorization": `Bearer ${API_KEY}`, 
                },
              }
            );
