When I am uploading practice tests csv file for my Udemy course, I get the error "Response does not include the base64 encoded policy!".

I followed the instructions and downloaded Udemy's Practice Test Question Template, and tried it both:

1.Uploading the file as it is(without changing anything.) (still got this error "Response......"

2.Uploading after adding my questions, still get the same error "Response...."

Anyone had the same issue and how did you fix that?

Thank you in advance.
