Nuxt SSR app crashing on Herokun with no meaningful error - vue.js

I have a Nuxt.js SSR application deployed to Heroku, when I try to visit the deployed app from the URL, I get an error that there's a server error.
When I check the logs, I get this error:
2021-02-25T16:12:24.942456+00:00 app[web.1]: ERROR Cannot find module 'defu' from '/app'

everything works fine during development and the builds are successful, I just cannot make sense of that error.
I have tried searching the project for the keywords "defu" or "/app" but I'm not getting any results, my app does not have a "/app".
I just don't know what kind of error this is.

SOS:: Hosted Google Reader Alternative project down on Heroku with timeout H12.

We have built an open-source, free Google Reader Alternative and have live users using the platform. It is hosted at http://reader.pykih.com and code is at http://github.com/pykih/reader
Until, last night my app was working fine and today morning it is down due to timeout.
We use DelayedJobs for all feed imports
This timeout is occurring on the homepage where there is no external service call, emails being set, etc. except may be push to GA
Heroku Support (as per them) is asleep right now and we will get an answer only on Monday. :-(
We went through a lot of past questions on Stack over flow about this issue but none seem to answer our issue.
Can someone please advice?

Heroku fixed itself 11 hours later. V annoying.

Heroku application error message

My app stopped working out the of the blue while I was using it, with the error message:
"An error occurred in the application and your page could not be served. Please try again in a few moments.
If you are the application owner, check your logs for details."
My logs file is below, and I'm suspecting this is a problem at the heroku end, but it has persisted for over half an hour now.

Analytical gem on Heroku error

Good morning. I am trying to use this gem:
https://github.com/jkrall/analytical
On Heroku. It runs dandy on my local environment, but on Heroku busts out with:
2012-10-31T13:52:28+00:00 app[web.1]: /usr/local/lib/ruby/1.9.1/syck.rb:135:in `load': syntax error on line 4, col 5: `' (ArgumentError)

2012-10-31T13:52:28+00:00 app[web.1]: from /app/vendor/bundle/ruby/1.9.1/gems/analytical-3.0.12/lib/analytical.rb:13:in `open'

2012-10-31T13:52:28+00:00 app[web.1]: from /app/app/controllers/api_controller.rb:1:in `<top (required)>'
The line in "api_controller.rb" it is references is simply the "analytical" statement that initializes the gem in that controller, per the documentation.
Tried putting "analytical" in application_controller instead and it errored out too (in both dev and staging).
Totally stumped. Any help would be much appreciated!
When I had a similar problem, the issue turned out to be a syntax error in my config/analytical.yml file. In development, I was able to put my Google Analytics ID in without quotes around it, but on Heroku it gave this error. So instead of this:
production:
google:
key: UA-XXXXXXXX-X
I did this:
production:
google:
key: "UA-XXXXXXXX-X"
Also, possibly you need to make sure there's a trailing carriage return after that last line

500 internal server error when I try to push my app onto Heroku

I am facing this problem upon pushing my app to Heroku:
500 internal server error
ActionView::Template::Error...application.css isn't precompiled (see attached Heroku logs)
Also, ActionController::RoutingError (No route matches [GET] "/assets/rails.png"
I am using Twitter Bootstrap 2.0.1 and Rails 3.1.1 (see Gemfile below)
Any guidance would be much appreciated!

HEROKU INFO
=== weddoo
Addons: Shared Database 5MB
Database Size: 64k
Dynos: 1
Git URL: git#heroku.com:weddoo.git
Owner: postkhalid#yahoo.com
Repo Size: 11M
Slug Size: 11M
Stack: bamboo-mri-1.9.2
Web URL: http://weddoo.heroku.com/
Workers: 0
So based upon the heroku info that you provided I see that you are on the bamboo stack and that stack does not support Rails 3.1+. Only the cedar stack supports Rails 3.1+. You'll need to use the following command to create a new app on the cedar stack:
heroku create --stack cedar
This is the result of your stylesheets not being compiled. Heroku will attempt to run
rake assets:precompile
before deploying your app. If the precompile command fails it will fail silently for now. I actually have an open issue for this on Heroku
https://github.com/heroku/heroku-buildpack-ruby/issues/9
The most likely cause is that the Rakefile is trying to load (or access) a gem. Heroku buildpacks attempt to compile the stylesheets before they have access to the gemset so any requires will fail. The best way to avoid this is to wrap those requires in your Rakefile in environment specific conditionals:
if Rails.env == 'development' || Rails.env == 'test'
require 'somegem1'
require 'somegem2'
# whatever code is being used by those gems goes in this block
end

Spawn gem on heroku - "PGError: server closed the connection unexpectedly"

I'm using the Spawn gem in a rails 3 app - it's the rails3-adapted fork at https://github.com/rfc2822/spawn
My app is deployed on heroku, and when i tried to spawn i get this failure:
app[web.1]: ### ../controllers/messages_controller.rb:10:in `create_message': About to spawn
app[web.1]: spawn> parent PID = 1
app[web.1]: spawn> child PID = 49
app[web.1]: ### ../controllers/messages_controller.rb:17:in `create_message': After spawn
app[web.1]: Task Load (1.2ms) SELECT "tasks".* FROM "tasks" WHERE "tasks"."id" = 80 LIMIT 1
app[web.1]: PGError: server closed the connection unexpectedly
app[web.1]: This probably means the server terminated abnormally
app[web.1]: before or while processing the request.
I have this option in my config/database.yml, following the recommendation of the spawn documentation:
reconnect: true
Is it connected to this do you think?
Bit at a loss with this... before i go investigating, does anyone know what's causing this?
cheers, max
I ended up using the girl_friday gem instead, which is a simple forked-queue system. It worked great for me.
