This is actually not an issue. It is just a message to let the user who is testing the package with the example file, know that i don't handle this case on this page.But this don't prevent you to use the package with PDF files as you may see. The Package has saved as expected the file in the Database so from there, nothing prevent to serve it in the browser. I will show a simple way to serve it in the browser.
Get back to the testHBFWPDO.php file and go to the line 45 .You error message is there
