incorrect attachment size limit

From your documentation:

The 100MB size limit on attachments in Asana is enforced on this endpoint.

But, you never fixed that issue, your nginx server is still blocking at around 30M, with error
413 Request Entity Too Large

It’s not a new issue, we had to block at 30M since day 1 of using your api to upload attachments, in 2016.

I don’t believe so, I very often upload attachment of 60 or 70Mo…
