Flutterfire: [firebase_messaging] ERROR ITMS-90771: "Missing Info.plist value. The Info.plist key 'BGTaskSchedulerPermittedIdentifiers' must contain a list of identifiers used to submit and handle tasks when 'UIBackgroundModes' has a value of 'processing'

[insinfo]

After I added firebase message to my flutter project and implemented it as described in the pub.dev readme, when I sent the app to the Apple App Store this error appeared right on uploading.

ERROR ITMS-90771: "Missing Info.plist value. The Info.plist key 'BGTaskSchedulerPermittedIdentifiers' must contain a list of identifiers used to submit and handle tasks when 'UIBackgroundModes' has a value of 'processing'.

Hi @insinfo, I added a value like this and app runner validate success. I don't know root cause and maybe it will make a bug.

<plist version="1.0">
<dict>
    <key>BGTaskSchedulerPermittedIdentifiers</key>
    <array>
        <string>com.your-domain.app</string>
    </array>
</dict>
</plist>

[tyegah]

@kimthangatm Hi, where did you put that plist file/value? I am experiencing the same thing

[kimthangatm]

@tyegah, The error is ERROR ITMS-90771: "Missing Info.plist value. The Info.plist key 'BGTaskSchedulerPermittedIdentifiers' must contain a list of identifiers used to submit and handle tasks when 'UIBackgroundModes' has a value of 'processing'. For more information....."

So you put this information to [YOUR_PROJECT_DIR]/ios/Runner/Info.plist

The value com.your-domain.app is your PRODUCT_BUNDLE_IDENTIFIER

Example:

<?xml version="1.0" encoding="UTF-8"?>
