Deploying meteor to Heroku serve : Application error - ruby-on-rails

As a beginner with those tools, i followed tuto i found on the web to help me starting my app.
Here are the exacts commands i runned on ubuntu to deploy the todos example app from meteor and testthe whole thing.
meteor create --example todos
cd todos
git init
git add .
git commit -m "my first commit"
heroku create test2-push --stack cedar --buildpack https://github.com/AdmitHub/meteor-buildpack-horse.git
heroku config:set BUILDPACK_URL=https://github.com/AdmitHub/meteor-buildpack-horse.git
heroku addons:add mongolab
git remote -v (vérification validité repo)
git push heroku master
But I'm having some trouble,as you can see here : http://test2-push.herokuapp.com
When i look at the logs, this is what kind of report i see :

It seems that i got several problem with fibers and router, often getting the exit status 8, but i do not understand a lot about that logs, and haven't found yet any explanation on the web.
Would someone have an explanation for me ?
Thanks you.

I had possibly the same issue. I completely fixed mine by setting the buildpack differently:
heroku buildpack:set https://github.com/AdmitHub/meteor-buildpack-horse.git -a YOUR_APPNAME

For me it was not setting the aws credential. I forgot to do it when I created a new app that was cloned and modified from an already working project. I found this by opening the rails console and doing a heroku restart.

Application error on Heroku. An error occurred in the application and your page could not be served

I have deployed my first app on Heroku. The app was working. I did some css styling, added a gem and added a widget. After pushing to Heroku I started getting this error.
Application error,
An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details.
I deleted all changes and deleted the gem and I'm still getting the same error.
Can someone please help.
This is what my logs says.

Hartl's Ruby on Rails / Hello_App / Heroku Error H10

I have coded the very simple app titled "Hello_App" from Hartl's Ruby on Rails. I followed all Hartl's instructions very closely. Everything worked fine locally. But when I attempted to deploy the app using Heroku, it crashed. I am stumped and don't know where to start.
Part of the Heroku log with H10 errors appears below. At your request, I have added more from Heroku log.
