App error, pushed to heroku Missing template

I'm attempting to deploy a rails webapp on Heroku using Cloud9. This might be a precompiling asset problem. I checked the heroku error logs and the error says Action Controller: Exception Caught
Everything works fine on my local machine, there is just something going wrong when pushing to heroku.

raise_in_transactional_callbacks issue with paperclip (rails 4.2)

I've updated to rails 4.2. When I follow up on deprecation warnings and set config.active_record.raise_in_transactional_callbacks = true in my environment, I start running into issues:
Failure/Error: Unable to find matching line from backtrace
NoMethodError:
undefined method `id' for nil:NilClass
The id refers to current_user.id, which has become unavailable (hence the warden and devise mentions in the error trace).
When removing config.active_record.raise_in_transactional_callbacks = true, deprecation warnings appear only with respect to two models that use paperclip, which leads me to believe that this might be an issue with paperclip callbacks. I could just ignore the deprecation warnings, but i'd rather fix the underlying issue. Any suggestions?
Here's an error trace:
commpleted 500 Internal Server Error in 152ms
Unexpected error while processing request: undefined method `env' for nil:NilClass

Here is the issue related to what you say : https://github.com/thoughtbot/paperclip/issues/1933 (especially my comments : https://github.com/thoughtbot/paperclip/issues/1933#issuecomment-169607838 and https://github.com/thoughtbot/paperclip/issues/1933#issuecomment-170509222 )
Please note that this warning is not an error, it only tells you the futur behaviour of ActiveRecord, which is not to shallow error.
Removing config.active_record.raise_in_transactional_callbacks = true will show you the warning of after_commit / after_rollback and switch to the old behaviour, which is shallowing errors.

Error receiving binary files in Rails 4.2 and Ruby 2.2.0

We were upgrading to Rails 4.2/Ruby 2.2 (from Rails 3.2-stable/Ruby 2.1.5) at work when we realize that something before worked fine now it doesn't.
Receiving a binary file from a external service (Unity app) the error was this one:

We use WWWForm.AddBinaryData from Unity side. Encoding: text/html; charset=ASCII-8BIT. Example:
form.AddBinaryData("image", jpegEncoder.GetBytes(), "imageName", "text/html; charset=ASCII-8BIT");
We searched in Rails changelog but we haven't seen anything new related.
Finally we moved to a different approach: this service provides a Base64 string and it works fine (but 30% aprox. weighter), so would be nice if someone has any idea about it.
In case anyone else runs into this, I've forked Rack and fixed it so that this error isn't thrown:
https://github.com/ianhirschfeld/rack
Essentially, I had to manually check the encoding for Unity's funky "utf-8" string and then force it to UTF-8 which Rack handles properly.

And here is the haml file mentioned in the error log
_promos.html.haml
.promos
.item
-if #token_shop_promotion
-if #token_shop_promotion.link == "empty"

-else
= link_to(image_tag(#token_shop_promotion.image.url, :alt => #token_shop_promotion.title, :height => 456, :width => 444), #token_shop_promotion.link, :target => 'blanck')
It seems that #token_shop_promotion is an array in your partial, when you expect it to be a singular object. Make sure the data is what you expect it to be, the is pretty much the first step/rule in any debugging scenario.
In your case it seems that you assume the data you are using to be different, it fails because of that and instead of verifying your assumptions, you go on a wild goose hunt :)
Reminds me of this blog post, read it :)

Rails gives me an unique error: RuntimeError: Session collision

I get this error:
RuntimeError: Session collision on '"6a17879bbd78f0ee4dbc823e3cd50682"'
The app is configured using: unicorn, memcached.
session_store.rb is:
Bulevard::Application.config.session_store :mem_cache_store, :key => '_bulevard_session', :expire_after => 10.minutes
production.rb is:
config.cache_store = :mem_cache_store
