Running Python script from Azure WebJob

I'm trying to run python script from Azure webjob. This is what I've done following this link

  1. Access the kudu tool via the url https://<webapp name>.scm.azurewebsites.net and installed Python 364x86 via Site Extensions tab
  2. Confirmed Python 364x86 is installed in the following path: D:\home\python364x86
  3. Added my script trading.py in D:\home\python364x86
  4. Created run.bat file with this line of code D:\home\python364x86\python.exe trading.py
  5. Included run.bat and trading.py in the webjob zip file
  6. Deployed, but getting error
[09/07/2019 07:02:00 > 0dd02c: SYS INFO] Status changed to Initializing

Functions.cs

public void StartTheBot()
        {        
            // Local   
            //var fileName = @"C:\Users\robert\AppData\Local\Programs\Python\Python37-32\python.exe";
            //var script = @"C:\python-scripts\trading.py";

            // Production
            var fileName = @"D:\home\python364x86\python.exe";
            var script = @"D:\home\python364x86\trading.py";
            var errors = "";
            var results = "";        

            ProcessStartInfo psi = new ProcessStartInfo
            {
                FileName = fileName,
                Arguments = script,
                UseShellExecute = false,
                RedirectStandardOutput = true,
                RedirectStandardError = true,
                CreateNoWindow = true
            };            

            using (Process process = Process.Start(psi))
            {
                errors = process.StandardError.ReadToEnd();
                results = process.StandardOutput.ReadToEnd();               
            }

            Console.WriteLine("Errors:");
            Console.WriteLine(errors);
            Console.WriteLine();
            Console.WriteLine("Results:");
            Console.WriteLine(results);
        }

Above code executes python script. It works locally, but once I deploy it to production it fails. Tried so many times, spent plethora of hours, but still unsure why prod doesn't work. Help is appreciated.

trading.py

import telegram

my_token = 'mytoken'
bot = telegram.Bot(token = my_token)

chat_id = 'mychatid'
message = 'Hello
bot.sendMessage(chat_id=chat_id, text=message)
