cancelPayload() throws ApiException: 8014: STATUS_PAYLOAD_UNKNOWN

[Luosoha]

This is the exception message that I got from calling cancelPayload().

nearbyConnectionsClient.cancelPayload(payloadId)
        .addOnFailureListener {
              // com.google.android.gms.common.api.ApiException: 8014: STATUS_PAYLOAD_UNKNOWN
        }

So here is what happened:

First, I create multiple payloads from files then send them with something like this:

payloads.forEach {
        Log.d("hails", "sendFilesAsPayload: ${it.id}")
        nearbyConnectionsClient.sendPayload(endpointId, it)
}

Then while the files are being transferring, I call cancelPayload() on the last payload (or any payloads that hasn't started yet). And so the exception gets throw on addOnFailureListener.

I did made sure to call cancelPayload() on the correct payloadId (I logged them and the one being sent and the one being called cancel on has the exact same id).

Any ideas or suggestions on which has caused the exception would be appreciated.

For short, cancelPayload() just is not working for me.
