Asana - Salesforce Integration - Action upload a file

We are using Zapier / Asana, Attach File Action.

We have Project Object in Salesforce. The Project object has Notes and Attachments (files). We want to create the project and then upload the file as an attachment to a task.

We are trying to achieve the following:

  1. Create a project in Asana when a new SF object is created - this works
  2. Create a task in the project created in step 1. - not working
  3. Upload a file to the task created in Step 2, using the Upload File action in Asana.

Has anyone attempted this using Zapier?

Thanks
