how to run fastapi app from different path - heroku

my repo directory looks like
src/
notebooks/
web/
one/
two/
app/
when I am under two I can lunch my fastapi app using
uvicorn app.app:app --reload --host=0.0.0.0 --port=7000
however, I am going to deploy my model on heorku and the Procfile should be at the main path. I know I have to make a Procfile and add
web: uvicorn app.app:app --reload --host=0.0.0.0 --port=7000
but I can't run the app from other folders. It would give the error
ModuleNotFoundError: No module named 'app'
UPDATE
the output of find web/two/app is as following
so when I run uvicorn web.two.app.app:app --reload --port=7000
the error is

You have to provide the entire path from root to the app. In your case it should look like this:
uvicorn web.two.app.app:app --reload --host=0.0.0.0 --port=7000

where to add "gunicorn hello:app --timeout 10" parameter?

I need to add Gunicorn parameter --timeout 600. Where should I add it? My project contains a Procfile, server.py and Jupyter notebook and requirements.txt.
Your Procfile defines process types for Heroku to run. Yours likely contains a line like this:
web: gunicorn hello:app
This tells Heroku that you have a web process that can be started by running gunicorn hello:app. If you want to pass an argument to gunicorn, modify that line accordingly:
web: gunicorn hello:app --timeout 600
Commit that change and redeploy.

Heroku won't recognize Procfile in dynos at dashboard

Im trying to host my object detection api on heroku but i can't due to it not recognizing my
Procfile, which is a file and not a text file. the way its spelled is Procfile, its contents are
web:gunicorn app:app
the way i know that its the Procfile thats the problem is because when i run bash and look at the root directory of the heroku git i see Procfile but when i look at the logs i see that no web process is running and on the dashboard the dynos is completely empty.
i've tried doing
web: gunicorn app: app instead of web:gunicorn app:app
to no avail, i've made sure that gunicorn is in the requirements.txt and know that its pip installing the requirements.txt as the cmd tells me that it is when i do git push heroku master. i've tried doing echo>Procfile and then modifying the contents of the file. i've tried both echo "web:gunicorn app:app"> Procfile and echo web:gunicorn app:app>Procfile i tried doing heroku ps:scale web=1 and get Scaling web dynos... failed ! No such process type web defined in Procfile. and when i do heroku ps i get nothing

Heroku Discord Bot builds but doesn't work

I am trying to host a discord bot on Heroku (Discord JDA, Maven). I do this by connecting to Github and then deploying. The bot 'deploys' (view attachment) but doesn't actually work (view attachment).
What could I be doing wrong, or has anyone else come across a similar issue?
Quick and dirty way to deploy it:
You'll need to setup a Procfile, extensive info on that right here: https://devcenter.heroku.com/articles/procfile
The procfile is basically a file with no extension that tells the dyno how to execute your program.
A simple
worker: java $JAVA_OPTS -jar <PATH_TO_JAR>
will work fine if you don't need more config, refer to that link for more.
You can then deploy it like this (Good to have procfile and jar on the same directory):
$ heroku deploy:jar -a <YOUR_HEROKU_APP_NAME> --jdk <JDK_VERSION> --jar <PATH_TO_JAR> -i Procfile
Then to start it just do (Assuming you want a worker dyno, which is what discord should need)
$ heroku ps:scale -a <YOUR_HEROKU_APP_NAME> worker=1
Then stop it with:
$ heroku ps:scale -a <YOUR_HEROKU_APP_NAME> worker=0
I've found this is much simpler than using git, especially if you're doing tests or simple/quick stuff.
Possible solutions:
Set up a Procfile. A Procfile basically tells Heroku what command to run when your app is deployed. Inside the Procfile, write worker: node index.js. Also, make sure Procfile has a capital "P".
Set up package.json.
npm init
Then just skip through the set up and your file should be automatically created. IMPORTANT. In your package.json file, add your node and npm versions.
node -v
npm -v
Then go an type this in your package.json.
"engines": {
node: "your-version-here"
npm: "your-version-here"
}
Then try deploying your app to Heroku again. Also, make sure you have the "nodejs" buildpack set up for your app. Run it and test the discord bot.

AngularJS - Deploy on Heroku

I created a app for Angular manually, his structure and all stuff.
To run it locally I'm using http-server.
How can I deploy it to Heroku in order to inform what server to run (probably in Procfile)?
Create a Procfile just called Procfile (no extension) in the root of your app. Within that file use web: to tell heroku what to run. For example:
web: coffee server.coffee

HEROKU: ps:scale web=1 no such process type web defined in Procfile

I have seen very similar posts, that however did not help me to find a solution to my problem.
I am following step by step the guide to upload a project on heroku.
However when I type the command:
ps:scale web=1
The result is:
no such process type web defined in Procfile
I have created a file "Procfile" being careful at the capitalization. but nothing.
What else can I do to solve this problem??
Thanks in advance.
Follow on this heroku procfile
:
We have to define web process type in your Procfile and make sure name Procfile exactly, and not anything else. For example, Procfile.txt is not valid.
Example:
a: Python:
web: gunicorn gettingstarted.wsgi --log-file -
b: String MVC Hibernate
web: java $JAVA_OPTS -jar target/dependency/jetty-runner.jar --port $PORT target/*.war
This declares a single process type, web, and the command needed to run it. The name web is important here. It declares that this process type will be attached to the HTTP routing stack of Heroku, and receive web traffic when deployed.
Procfiles can contain additional process types.
worker: bundle exec rake jobs:work
Hopefully you've fixed your problem after all this time, but just in case you haven't...
I've run into this problem when my Procfile doesn't exist (a web app that I'm porting to Heroku) or doesn't match the dyno type that I'm trying to deploy (see Heroku No such process type web defined in procfile for an example of that).
You've created your Procfile, but what did you put in there? For a website Node.js app, you'll need to put in:
web: node app.js
(Obviously you'll replace app.js with index.js or wherever your app starts)
For more about Procfiles (or for other languages than Node.js), see https://devcenter.heroku.com/articles/procfile
