Hello! I'm struggling trying to attach a pdf file to a homework. When I click on the "Entregar" (submit) button, It just starts loading and after a few seconds the page gets bug and the "Entregar" button gets dissabled. I've been trying since yesterday switching from my internet network, from my phone, with different file names, browser, etc. And It always displays that message on the console (the web itself doesn't show anything, I have to open the development environment to see it).
