Twitter Image Upload 400 Error

I am trying to use the Twitter Image Upload workflow and I get the following error. I have download workflow that downloads and saves the image. I believe that works as I get a 200 back and a file path. That file path is then used in the Twitter Image Upload workflow. What could I be doing wrong?

{
"error":{
"name": "Error"
"message": "HTTP Error: 400 Bad Request"
}
}

Hi Rob,
Can you please provide the below details for finding the issue, As it is working for me

  1. What is the file path you are giving to download the file.
  2. What is the image size you are trying to upload.
