Cannot download files from tasks

[Conner_Meyer_Gulled1]

When I try to download an attachment from a task, it opens a browser tab with the following message:
function func(allowed_types) { assert_9.default.ne(undefined, allowed_types, name + " was passed undefined. You probably didn’t mean " + “to call it as a function.”); return new TypeCheckedAttribute(allowed_types instanceof Array ? allowed_types : [allowed_types], func); }

Error

Forbidden

I was experiencing this issue as well. I cleared my Asana cookies, restarted Asana, logged back in, it now I can download attachments again!

Clearing my browser cookies did the trick, thank you!
