I just tried to deploy my first heroku application, but unfortunately I am getting an error.
The command heroku logs --tail throws the following error:
2020-02-14T16:35:34.990792+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/"host=agile-wildwood-52268.herokuapp.com request_id=5edfe87f-b4c7-42ee-a856-03ab806613ec fwd="88.68.64.245" dyno= connect= service= status=503 bytes= protocol=https

I don't know where this error might be caused, any help is appreciated. Thank you
So I figured out the problem.
I didn't have my environment variables set on the heroku dashboard.
If you get a similar problem follow those steps:
Go to https://dashboard.heroku.com/apps
Click on your application
Go to settings and click on "reveal config vars"
Enter all your environment variables
Hope it helps

I have a frontend only app that was successfully built and deployed by heroku. But when I run it I get this error:
GET https://decoder-app.herokuapp.com/ 503 (Service Unavailable)
heroku logs --tail says this:

The error is
no main manifest attribute, in target/qrcodegen-1.0-SNAPSHOT.jar
Without any main attribute Java does not know which class to execute.
Normally the spring-maven-plugin will rewrite the built jar and add needed metadata such as a main attribute. You seem to be missing that plugin
I tried to run the web-assembly of this https://github.com/syncfusion/blazor-showcase-appointment-planner in Heroku.
I added the buildpack https://github.com/jincod/dotnetcore-buildpack in Heroku, and try to deploy it. Here is the log after building it in Heroku:

I tried to remove web-assembly away from the folder tree, and move its contents to the root of the repository. I then get:

Can anyone deploy the app in Heroku, or spot any error in the deploying process?
So, for anyone with the same problem here. It's not the desired solution, but it works. I didn't manage to push my Blazor WASM project neither to Heroku (with .net buildpack) nor to GH pages.
Push your static Blazor WASM to Cloudflare pages -

Literally zero problems happened - push to github, paste build command in cloudflare pages interface - Deploy

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

If you are using virtul environment in your app then you have to pip install gunicorn and create a procfile and then you have to write a single line in that procfile so that heroku can detect it, see the below video for help.

I have created a react app with nodejs, I am getting an application error while starting my heroku application. I have updated heroku, created procfile, added node as engine. Still my application is not starting. Please help.

Heroku by default uses Node.js build pack, which would not work for a react app, you would not have to change the build pack in the setting of that project.
