When file size is larger, validation error is not passed "undefined method `errors' for nil:NilClass"

[basicavisual]

Steps to reproduce:

1. Upload a file larger than the maximum allowed size
2. You will find an error as follows
   

On examining create_document.rb:25 on runtime, document variable returns nil. However, create_document is correctly raising an ActiveRecord::RecordInvalid validation error so my guess is that the way in which the begin / rescue statement is written is not allowing the document variable to be passed to the rescue block.

However, I think the pattern is correct and should be passing that variable... here's an example of such pattern on the decidim gem. I can't figure out the reason why the document variable is not passing, but if anyone has a clue I'd be happy to contribute

Hi @basicavisual we've introduced new validations in the document.
Could you check if this is still happening?

Hey there! did a test today and I'm getting the same error but I noticed your commit #98 is this the one you are referring to? because that one's about suggestion lengths, I meant the issue to pertain PDF file size, so, more related to #101

Specifically by this line seems like the document variable is nil. Are you able to reproduce?
