Hi Team,

  I have requiremnet to download a file and upload the same file in my script. Currently i am not able to download file and save the file locally.

When i tried checking by adding below function, to check the file is being downloaded or not. Below ducntion does shows the data is being downloaded. I want to save the file and upload in next step.

I have checked the reponse body of download function, the data or the file content is not available.
