Error message when attempting to download doc

I’m a beginner working through the Gregory John video series of building a job board and I can’t seem to get past this hiccup.

I run into this error message when I try to download a CV from a sample applicant:

{“error_class”:“Unauthorized”,“args”:{“code”:“1774219818022x673725232692177900”},“message”:null,“translation”:“Permission denied”}

I’ve gone through the workflows and the privacy settings and I’m obviously missing something. I would appreciate anyone pointing me in the right direction.

Here’s a screen shot of the pop up and property editor.

Here’s the url after the download attempt:
…test/fileupload/f1774090041679x451417506320706400/Peter-Hudson-CV.pdf

Like I said, if you can point me in the right direction I’d appreciate it. Thanks.
