flask html link for downloading file

Question

I'm building an websites that allows the user to download files from my server. I wrote a route for serving the file:

@api.route('/download_results/<path:filename>')
def download_results(filename):
    return send_from_directory(app.config['UPLOAD_FOLDER'], filename, as_attachment=True)

if i try to use an html tag like this:

<a class="btn btn-primary" herf="http://localhost/api/download_results/1234567890/results.zip" download="results.zip">Download results</a>

it doesn't work. but if i add an event listener in jQuery:

$('a').on('click', function(event) {
     event.preventDefault();
     window.location.href = location.origin + '/api/download_results/' + data.parsedData[0];
 });

it works and i can download but i get a warning:

Resource interpreted as Document but transferred with MIME type application/x-zip-compressed: " http://localhost/api/download_results/1234567890/results.zip ".

Anyone knows what i'm doing wrong and how i can solve this? Thanks!
