Create a task with attachments in Asana using Asana api

Question

I am trying to send an image using Asana's API but it just attaches a blank file. This is the code I have been using.

client.attachments.create_on_task(task_id=123456789,file_content="Url_of_file",file_name='Name_of_File',file_content_type="image/jpeg")

I have tried using different file formats like .txt and .png but for some reason the Asana API is blocking my requests.It just posts a black image on Asana. I have tried to convert the file to base64 as well but it still doesn't work

In this original documentation(below), it shows that we need to pass two arguments;one for the file's content and the other for file itself ('file').

def create_on_task(self, task_id, file_content, file_name, file_content_type=None, **options):
        """Upload an attachment for a task. Accepts a file object or string, file name, and optional file Content-Type"""
        path = '/tasks/%d/attachments' % (task_id)
        return self.client.request('post', path, files=[('file', (file_name, file_content, file_content_type))], **options)

But when I am trying to pass the arguments for file and file content it shows me an error.

Can somebody please help me with this?

Another user on the Asana development forum had the same problem using the Curl API. (https://forum.asana.com/t/sending-file-with-api/16897/2). Apparently it has something to do with the 'multipart form upload'.

Looking through another thread here on stackoverflow (How to send a "multipart/form-data" with requests in python?), it seemed the file object had to be read in binary was all.

so the parameters would be:

client.attachments.create_on_task(task_id=<task id here>,file_content=open(filename_with_path, 'rb'),file_name='Name_of_File',file_content_type="image/jpeg")
