Firebase cloud function http request crashing

问题

I'm trying to send expo push notification via firebase cloud functions, in order to send notifications from the web app to devices that have downloaded the mobile app.

When I send the request from Postman, it works just fine... i get the ok response and the notification shows up on my phone. But when I try to make the request from the web app, i get this in the functions log:

Function execution took 22 ms, finished with status: 'crash'

Any ideas why is this happening? Couldn't find anything to explain this so far.

Here's my function:

exports.reportNotification = functions.https.onRequest((request, response) => {
    const tokens = request.body.expoPushToken;
    let messages = [];
    tokens.forEach((token) =>
      messages.push({
        to: token,
        title: "title",
        body: "message",
        sound: "default",
        _displayInForeground: "true",
      })
    );

    fetch("https://exp.host/--/api/v2/push/send", {
      method: "POST",
      headers: {
        Accept: "application/json",
        "Accept-encoding": "gzip, deflate",
        "Content-Type": "application/json",
      },
      body: JSON.stringify(messages),
    })
      .then((res) => response.status(200).json({ res: res }))
      .catch((err) => response.status(400).json({ error: err }));
});

My post request on Postman:

{
    "expoPushToken": ["ExponentPushToken[xxx-xxxxxxxxxxxxx]"]
}

And I call the function with axios in the web app:

axios({
    url: "reportNotification",
    baseURL: functionsBaseURL,
    method: "post",
    data: {
        expoPushToken: tokens,
    },
})

I checked and the tokens on this request are in the same format that the one on Postman.

Thanks.

It was a cors problem, solved with this modification:

exports.reportNotification = functions.https.onRequest((request, response) => {
  cors(request, response, () => {
    const tokens = request.body.expoPushToken;
    let messages = [];
    tokens.forEach((token) =>
      messages.push({
        to: token,
        title: "title",
        body: "message",
        sound: "default",
        _displayInForeground: "true",
      })
    );

    axios.post("https://exp.host/--/api/v2/push/send", JSON.stringify(messages), {
      headers: {
        "Accept": "application/json",
        "Accept-encoding": "gzip, deflate",
        "Content-Type": "application/json",
      },
    })
      .then((res) => response.status(200).json({ res: res }))
      .catch((err) => response.status(200).json({ error: err }));
  });
});
