It looks like the files weren't all sent to Heroku.
If you're deploying with git, make sure that all files are being shipped to the slug.
In your place, I'd try inspecting the contents of the slug by doing heroku run bash -a name-of-your-app and check if all files are where you'd expect them to be.


#elias Well I wish I tried that first. Not sure what it ending up being but I just rebuilt the entire app one part at time deploying to heroku as I added in parts to see what may have been causing the issue. Unfortunately I never did, however the app works now.
So yeah something was not being pushed up when I tried uploading the app as whole.
Thank you to everyone for the assistance on my first post!

As you can see the error is
node:events:491
throw er; // Unhandled 'error' event
SocketClosedUnexpectedlyError: Socket closed unexpectedly
and the weired thing is heroku immediatly rebuild the app?!!! I think it should only restart. am i right?
My question is how to know the cause of this error??
how to resolve this error?
Because my app got rejected in final review because of this error since shopify app send me below screenshot while the are reviewing my app
Yes heroku is displaying this error but after a while(after rebuild) the app again because accessible and works fine
and after successfull installation by 1 min the error occur and heroku rebuild the app again.
Any help is appreciated and thanks in advance

I have found the cause of this issue:
my node version in package.json was >=16.13.0 after making it 16.13.0 and deploy to heroku the app crash and rebuild after 15 minutes of the first deploy and then crash then rebuild and again after 15 minutes apps crash again. After it was crashing within the 1st minute.
Again to resolve the new issue explained above I have similar issue in redis node repo, saying that i have to extend client-output-buffer-limit and maxmemory while in heroku free plan for redis you can't access redis CONFIG command at all. So, I have found another alternative which is using free plan of RedisLabs and the issue of crashing is resolved and my app is working fine now.

How do I update my Heroku app without "Application Error"

This is the result when I open the app in heroku after doing an update.
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. You can do this from the Heroku CLI with the command
heroku logs --tail
This was the procedure I did when doing the updates:
heroku login
heroku info
heroku git:remote --app tcwhais
git add .
git commit -m "first update"
git heroku push master
heroku open
Because the web did not open, I did the following:
I installed the Heroku CLI (64-bit)
heroku login
heroku git:clone -a tcwhais
cd tcwhais
git add .
git commit -am"to correct error"
git push heroku master
heroku open
This is the logs of the updates:
PS C:\Users\User\Desktop\mysite\INO_TCWHAIS> heroku open
PS C:\Users\User\Desktop\mysite\INO_TCWHAIS> heroku logs --tail

JHipster Application doesn't be deployed to Heroku

I am trying to deploy my jhipster application to Heroku with yo jhipster:heroku command.But application doesn't start.
'heroku logs --tail' commands shows:

you need to set

config.action_cable.allowed_request_origins &
mount ActionCable.server in your route

Error deploying rails app on puma in Heroku

I am trying to deploy a rails app running on puma and jruby. the Procfile is as follows
web: bundle exec puma -C config/puma.rb -p $PORT -e $RACK_ENV
configuration for Puma placed in
config/puma.rb
if ENV['RACK_ENV'] != 'production' || ENV['RAILS_ENV'] != 'production'
workers Integer(ENV['PUMA_WORKERS'] || 4)
end
threads Integer(ENV['MIN_THREADS'] || 1), Integer(ENV['MAX_THREADS'] || 4)
rackup DefaultRackup
port ENV['PORT'] || 3000
environment ENV['RACK_ENV'] || 'development'
preload_app!
on_worker_boot do
# worker specific setup
ActiveSupport.on_load(:active_record) do
config = ActiveRecord::Base.configurations[Rails.env] ||
Rails.application.config.database_configuration[Rails.env]
config['pool'] = ENV['MAX_THREADS'] || 16
ActiveRecord::Base.establish_connection(config)
end
end
the reason I have a conditional initialisation for workers is because Heroku complains (or may be Puma) worker mode is not available for JRuby and Windows; anyway,
The strange behaviour I notice on heroku is that (unlike) my local environment a clustered Puma instance starts without any problems, and picks up two different ports to bind i.e. 3000 and 5000.
However, on production i.e. Heroku this causes a crash

This strange startup behaviour is not seen when I run it on my laptop.
The only way I have got puma working on jruby in Heroku is through this setting
if ENV['RACK_ENV'] != 'production' || ENV['RAILS_ENV'] != 'production'
workers Integer(ENV['PUMA_WORKERS'] || 4)
port ENV['PORT'] || 3000
environment ENV['RACK_ENV'] || 'development'
end
threads Integer(ENV['MIN_THREADS'] || 1), Integer(ENV['MAX_THREADS'] || 4)
rackup DefaultRackup
preload_app!
on_worker_boot do
# worker specific setup
ActiveSupport.on_load(:active_record) do
config = ActiveRecord::Base.configurations[Rails.env] ||
Rails.application.config.database_configuration[Rails.env]
config['pool'] = ENV['MAX_THREADS'] || 16
ActiveRecord::Base.establish_connection(config)
end
end
i.e. if the port and environment directives are out side the if block Heroku somehow tried to run two instances on the same port, which will obviously cause a crash.
Am I missing any configuration here or basically running in clustered mode (I even tried running on Ruby 2.0.0 instead of JRuby) is just not possible in Heroku
* Update *
Procfile
web: bundle exec puma -C config/puma.rb
config/puma.rb
if ENV['RACK_ENV'] != 'production' || ENV['RAILS_ENV'] != 'production'
workers Integer(ENV['PUMA_WORKERS'] || 4)
end
threads Integer(ENV['MIN_THREADS'] || 1), Integer(ENV['MAX_THREADS'] || 16)
rackup DefaultRackup

ActiveRecord::Base.establish_connection(config)
end
end
The reason for conditional block (quoted from initial problem description
the reason I have a conditional initialisation for workers is because
Heroku complains (or may be Puma) worker mode is not available for
JRuby and Windows;
And error logs (even if I remove JRUBY, the conditional worker block) and try to run on clustered mode

I just had right the same issue as you.
It seems like its related to the duplicate definition of the port
First in the Procfile and later in the config/puma.rb file
I removed the port from the Procfile (as well as the environment), as this is already defined in config/puma.rb.
web: bundle exec puma -C config/puma.rb
