When I start the app, I get error code H14: no web proccess running.
I've already seen this: Gradle java web app doesn't start on heroku
heroku, and I've tried to run the command, yet I get this error: couldn't find that process type (web).
What is going on?

I have created a MERN app and deployed it on Heroku But it works for a while and then gives Application error. However, the code is fine and on the localhost both the frontend and the backend with MongoDB work perfectly fine and are up and running. I have tried everything I found on the internet. Here's the list of things I've done:
Added the config vars on Heroku (in case someone thinks I forgot that)
Checked the Procfile whether there's any space error
Checked the package.json files and scripts
Tried to update the node_modules and restart Heroku
Made commits and tried to push on Heroku multiple times hoping it was a temporary error
But nothing seems to be working and it's still giving H10 errors. What can I try next?
I've previously deployed apps on heroku written in Rails and in Express.js, and never come across the concept of a Procfile before. Now that I've just gone to deploy a Flask app, I discovered this Procfile concept and found that the app would not run correctly without it. The Heroku docs say nothing about this being Flask-specific, and imply it's needed for all apps.
What's up with that? Why didn't I need it before, but needed it now?
In the package.json it tells Heroku how to execute the program. That's JavaScript specific. In other languages there is no such file hence the need for a Procfile.
Heroku needs to know how to execute your project.
One of our test apps got deleted recently. We're trying to track down how/why (suspicion is an error in an API call that we've made). Is there a way to get any logs from Heroku that shows who/when/how an app was deleted?
I wanted to deploy an simple static file serevr I built to Heroku but it seems as soons as it is deployed to heroku is crashes immediatly...
I never pushed an Go App to Heroku and I bet my ports config isw wrong...
What confuses me is that it passes th build process and it crashes immeditiatly...
I also uploaded the source code to Github: Sourcecode
I bet there are many errors in the code or something I didn't get right with port forwarding at Heroku but any advices or hints would be great!
My application hang up. Because of that I wanted to delete the application but it's not possible. OpenShift just shows me: "Unable to perform action on app object. Another operation is already running" when I want to delete the application from the web interface.
Unable to perform action on app object. Another operation is already running.
When I check the status of my application then it is unknown. It shows "unknown" for my Tomcat server and also for my database server.
What can I do now to get my app back to live?
It looks like your error is caused by intermittent API failures on OpenShift, so there is nothing that you can do (except you work for OpenShift).
You can check the OpenShift Online Status Page to see whether the API errors are still present. To receive the latest status updates you can also follow OpenShift Operations on Twitter or join this IRC Channel: #openshift on irc.freenode.net.
I think the problem will be resolved quickly.
This may be caused by Tomcat running out of memory. Try rhc app force-stop -a [your_app] in the rhc command line tools. This should kill all running threads in your app even if it's out of memory. Then, if you want to restart the app, use rhc app start.
