Firebase Storage works on desktop but -13010 error on device {Unity}

[Naren Keshav]

Development Platform: Mac OS 10.14.6

Unity Version : 2018.4.10f1

Target Mobile OS : iOS 13.0

Firebase Version : 6.8.0

 

Scenario

 

There is a file in the local disk which I want to upload it to a server. The file (_filePath) is checked for it's existence. If present the coroutine uploadADummyFIle() is called. Nothing else matters but a simple upload method.

 

Issue

It works perfectly on my desktop but when I build it on my iOS device - the task "_resultTask" is always faulted. The error code is -13010. The error is

https://firebase.google.com/docs/reference/unity/class/firebase/storage/storage-exception#errorobjectnotfound

 

Code 

private IEnumerator uploadADummyFIle()

{ // This coroutine is only call when _filePath as a file exists

StorageReference _fileReference = Session.StorageContentNodeFor(_fileName);

Task _uploadTask = _fileReference.PutFileAsync(_filePath, null,

     new Firebase.Storage.StorageProgress<UploadState>(_state =>

     {

         float _percentage = (_state.BytesTransferred / _state.TotalByteCount);

         Debug.Log("Progress => " + _percentage);

         

     }), CancellationToken.None, null);

_uploadTask.ContinueWith

   (_resultTask =>

   {

       if (_resultTask.IsFaulted == true)

       {

           int _error = getExceptionFor(_resultTask);

           UnityEngine.Debug.Log("Upload FAULTED");

           UnityEngine.Debug.Log(_error);// Always -13010

   

       }

       if (_resultTask.IsCanceled == true)

       {

           int _error = getExceptionFor(_resultTask);

           UnityEngine.Debug.Log("Upload CANCELLED");

           UnityEngine.Debug.Log(_error);

       }

       Debug.Log("Upload Completed -> " + _resultTask.IsCompleted);

   });

 }

int getExceptionFor(Task _errorTask)

{

      if (_errorTask.Exception is System.AggregateException _aggregateException)

      {

          if (_aggregateException.InnerExceptions[0] is StorageException _innerException)

          {

              return _innerException.ErrorCode;

          }

      }

      return -1;

}

Request

I am quite not sure why it works on my desktop machine but not on my iOS device. If you need any more information beyond what is listed above, please let me know. 

I would like to know why such a problem, how to move forward & if possible the solution itself. 

Thank you,

I missed a crucial part. In desktop environment, you don't need to append a File path with "file://" but you need to do for iOS device. 

so it is just 

            string _filePath = filePath;

#if UNITY_IOS && (!UNITY_EDITOR)

            _filePath = string.Concat("file://", filePath);

#endif
