I'm getting Push Notification problems: Error: Couldn't get GCM token for device


#1

Hello everyone, I’m receiving this error while working with Expo. This is part of my package.json:

{

“dependencies”: {
“axios”: “0.18.0”,
“expo”: “^28.0.0”,
“jwt-decode”: “2.2.0”,
“lodash”: “4.17.10”,
“moment”: “2.22.2”,
“moment-timezone”: “0.5.21”,
“polished”: “1.9.2”,
“prop-types”: “15.6.1”,
“react”: “16.3.1”,
“react-native”: “https://github.com/expo/react-native/archive/sdk-28.0.0.tar.gz”,
“react-native-dotenv”: “0.1.1”,
“react-native-modal-datetime-picker”: “5.1.0”,
“react-native-offline”: “3.11.0”,
“react-native-size-matters”: “0.1.2”,
“react-native-svg”: “6.3.1”,
“react-navigation”: “2.5.5”,
“react-redux”: “5.0.7”,
“redux”: “4.0.0”,
“redux-devtools-extension”: “2.13.5”,
“redux-persist”: “5.10.0”,
“redux-saga”: “0.16.0”,
“reselect”: “3.0.1”,
“styled-components”: “3.3.2”
},

}

As you can see, I’m using the latest version of Expo with its corresponding tools. Another thing that I did was making changes so FCM can work using this guide: Using FCM. I don’t know what else to do, it’s very frustrating.

Can you post your code here? It’s very hard to help you without that. A link to a Github project might work best.

I got “Error: Couldn’t get GCM token for device” as well.
I am just testing the push notification example on documentation, but it always throws Error: Couldn’t get GCM token for device when executing Notifications.getExpoPushTokenAsync().

I have tried both expo SDK25 SDK28 on android 8.0 and ios 10, and none of them can get GCM token.

Any thoughts?

Update:
Notifications.getExpoPushTokenAsync() works perfectly in my project after I start my project with expo start instead of react-natives-scripts start.


#4

Same for me, I’m using the same code as the doc describes (copy, paste)
Using SDK 29.0.0.

– EDIT –
Just saw this response. Maybe this is the causing the issue.


#5

Thanks, your responses were very helpful. I didn’t know that CRNA could have problems with Expo notifications.


#6

how did you fix it?
Tell me? please.


#7

Hi. Instead of using the command react-native-scripts start I’m using exp start which is the CLI tool from Expo: https://github.com/expo/exp. Doing this, the function Notifications.getExpoPushTokenAsync is working well again. I’m afraid that CRNA is outdated (no new commits in the past two months: https://github.com/react-community/create-react-native-app/issues/722) and that’s the reason why we have problems with Expo using CRNA.

So i am having the same issue, ive created a feature 2months ago based on https://docs.expo.io/versions/latest/guides/push-notifications which it worked great. But apparently as ive attempted to check it today i am receiving the " [Unhandled promise rejection: Error: Couldn’t get GCM token for device] " error . I created a new project from scratch using

  "expo": "^28.0.0",
    "react": "16.3.1",
    "react-native": "https://github.com/expo/react-native/archive/sdk-28.0.0.tar.gz"

copy /pasted the code from documentation and run my app with exp start . But still i am getting the " [Unhandled promise rejection: Error: Couldn’t get GCM token for device] " error on

let token = await Notifications.getExpoPushTokenAsync();

. Can anyone assist me please ?:slight_smile:


#9

@mits you should use exp start instead of react-native-scripts start. CRNA needs some updates to work again with Expo.


#10

As i mentioned i used exp start but still the error occurs, and i dont know why.


#11

Was able to resolve it by adding FCM details correctly. Thanks :slight_smile:


#12

I’m getting this issue as well. Has anyone notified React Native devs of the issue?

Using exp start appears to have worked. I also added the information for my Firebase account, but I can’t tell which of those changes caused the app to work. I’m not building the app as an android app, just running it through Expo.


#13

They said they used exp start and got the same issue…


#14

I’m confused. What is an “Expo” project then? My react native app uses Expo… I don’t get what that means.


#15

Im using exp start and still got problem :frowning:


#16

thank you very much! works for me.


Error: Couldn't get GCM token for device - Problem
#17

I’m also getting this error on Andriod. I’m using exp start and the code from the example. Is there a workaround, yet?


#18

This solved my problems, thank you


#19

@developer you also need to follow this FCM guide, it was very helpful for me.


#20

Thank you! Didn’t realize that that was required now. Everything seems to be working now.
