Expo 推送通知适用于 expo go 但不适用于 apk（生产）

Question

I'm trying to implement expo push notification . I did everything as the docs say. Created a firebase project and downloaded the google-services.json and uploaded the server key on the cloud messaging to expo servers using expo push:android:upload --api-key <your-token-here> ! so basically I did everything mentioned on their docs! My notifications works perfectly fine when I test it on the Expo GO ! but after I built an apk using eas build -p android --profile preview The notification doesn't pop up? the api that I send from says that the notification was sent but it doesn't show on the device, I read that notifications work on expo go and not apk because of the credentials. did I miss a step or something. When I go to the expo builds and go to the project credentials Two options pop up: One by the path of com.company.app and the other one : by Legacy ( classic build)!

app.json

{
  "expo": {
    "name": "myapp",
    "slug": "myapp",
    "version": "1.0.0",
    "orientation": "portrait",
    "icon": "./assets/icon.png",
    "userInterfaceStyle": "light",
    "splash": {
      "image": "./assets/splash.png",
      "resizeMode": "contain",
      "backgroundColor": "#ffffff"
    },
    "updates": {
      "fallbackToCacheTimeout": 0
    },
    "assetBundlePatterns": ["**/*"],
    "ios": {
      "supportsTablet": true
    },
    "android": {
      "googleServicesFile": "./google-services.json",
      "adaptiveIcon": {
        "foregroundImage": "./assets/adaptive-icon.png",
        "backgroundColor": "#FFFFFF"
      },
      "package": "com.hyrix.myapp",
      "useNextNotificationsApi": true
    },
    "web": {
      "favicon": "./assets/favicon.png"
    },
    "extra": {
      "eas": {
        "projectId": "ee001501-c3b5-402f-8a1d-914144496965"
      }
    }
  }
}

You could check the Android Studios's logcat after connect your android smartphone to your PC.

I've tried to debug the app in Android Studio's logcat and got the following error message:

'[expo-notifications] Error encountered while updating the device push token with the server:', '{"errors":[{"code":"VALIDATION_ERROR","message":"\"appId\" must be a string.","isTransient":false}]}'

What I did to solve this issue was set "applicationId" manually in the Notifications.getExpoPushTokenAsync() method. Ex:

Notifications.getExpoPushTokenAsync({applicationId: "xxxxxx..."})

The applicationId can be found in app's firebase config as appId . The method getExpoPushTokenAsync() can receive some parameters, maybe some of them are not being set correctly.
