Run fastlane process and redirect output

I've been trying to integrate fastlane to my workflow but I can't run and receive fastlane output in unity console.

This is the code I'm trying to run:

     static StreamWriter messageStream;
     static Process process = null;
 
     [MenuItem("Setup/Fastlane/Details/Check newest build number from iTC")]
     public static void CheckBuildNumberOniTC()
     {
         process = new Process();
         process.StartInfo.WorkingDirectory = Path.GetFullPath("build/fastlane);
         process.StartInfo.FileName = "/usr/local/bin/fastlane";
         process.StartInfo.UseShellExecute = false;
 //        process.StartInfo.RedirectStandardInput = true;
         process.StartInfo.RedirectStandardOutput = true;
         process.StartInfo.RedirectStandardError = true;
 
         process.OutputDataReceived += new DataReceivedEventHandler(DataReceived);
         process.ErrorDataReceived += new DataReceivedEventHandler(ErrorReceived);
 
         process.StartInfo.Arguments = "run app_store_build_number";
         process.Start();
 
 //        StreamReader reader = process.StandardOutput;
 //        string output = reader.ReadToEnd();
 //        Console.WriteLine(output);
 //        process.WaitForExit();
 //        process.Close();
 
     }
 
     void OnApplicationQuit()
     {
         if (process != null && !process.HasExited)
         {
             process.Kill();
         }
     }
 
     static void DataReceived(object sender, DataReceivedEventArgs eventArgs)
     {
         UnityEngine.Debug.Log(eventArgs.Data);
     }
 
 
     static void ErrorReceived(object sender, DataReceivedEventArgs eventArgs)
     {
         UnityEngine.Debug.LogError(eventArgs.Data);
     }

I've tried the commented out version as well... What can be wrong?
