FirebaseMessaging Failed to sync topics. Won't retry sync. INVALID_PARAMETERS

[wufei-limit]

I'm using firebase topic api as below:

val topics = originTopics.filter { it.matches(Regex("^[a-zA-Z0-9-_.~%]{1,900}")) }
val tasks = topics.map { topic ->
    FirebaseMessaging.getInstance().subscribeToTopic(topic)
        .addOnCompleteListener { task ->
            var msg = "Subscribed"
            if (!task.isSuccessful) {
                msg = "Subscribe failed"
            }
            Timber.tag("FcmUtils").d("subscribeToTopic: $topic result $msg")
        }.addOnFailureListener { e ->
            Timber.tag("FcmUtils").d("subscribeToTopic: $topic failed: $e ")
        }
}

Tasks.whenAll(tasks)
    .addOnCompleteListener { allTasks ->
        if (allTasks.isSuccessful) {
            Timber.tag("FcmUtils").d("subscribeToTopics: All successful")
        } else {
            val failedTopics = topics.filterIndexed { index, _ ->
                tasks[index].isCanceled
            }
            Timber.tag("FcmUtils").d("subscribeToTopics: all Failed to subscribe to ${failedTopics.joinToString()}")
        }
    }

but on some device . I get error: FirebaseMessaging Failed to sync topics. Won't retry sync. INVALID_PARAMETERS . The topic string is "type_period,lang_en,tz_115200" . This only happen on some device occasionally — it doesn’t always fail. How to fix this?

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Hi @wufei-limit, thank you for reaching out. Just to clarify, do you mean that the "type_period,lang_en,tz_115200" is the topic name?

i.e

 FirebaseMessaging.getInstance().subscribeToTopic("type_period,lang_en,tz_115200")
        .addOnCompleteListener { task ->
            var msg = "Subscribed"
            if (!task.isSuccessful) {
                msg = "Subscribe failed"
            }
            Timber.tag("FcmUtils").d("subscribeToTopic: $topic result $msg")
        }.addOnFailureListener { e ->
            Timber.tag("FcmUtils").d("subscribeToTopic: $topic failed: $e ")
        }

Also, can you share the Firebase Messaging version you're using? Thanks!

[wufei-limit]

No , each item separated by commas in "type_period,lang_en,tz_115200" is a topic name. so this string represents three topic names.
And firebase version is

implementation platform('com.google.firebase:firebase-bom:33.15.0')

Thank you for your clarification. I wasn't able to reproduce the issue on a similar Samsung device and Android version.

By any chance, were you able to reproduce the issue? Could you provide the steps or more details?

I found a similar old issue reported in the Firebase iOS SDK (iOS/2625), and was already resolved. For now, I would suggest try updating to the latest Firebase SDK version. This is to ensure that you have the latest improvements and bug fixes.

[wufei-limit]

I can’t reproduce the issue consistently on my side either. When it happens, it usually occurs several times in a row, but after restarting the device a few times or waiting for a while, it recovers.

Can’t you locate the cause based on the error message “INVALID_PARAMETERS”? I haven’t found any invalid parameters in my implementation.

Also, when this issue occurs, neither the onCompleteListener nor the onFailureListener of the subscribeToTopic task are triggered. Is this behavior a bug or intentional?

I’ll try updating to the version you suggested. I’m still very curious about the root cause of this issue.
