Make Http Call From Node To Python In Heroku Dyno

I've inherited a repository that contains both a NodeJS part and a Python part. The project structure is such that the NodeJS is at the root of the repository, and the Python piece

Solution 1:

Finally found it. Dynos can't communicate with each other via HTTP, only via queues. I can't find it in the docs anymore, but they state it somewhere.

So I changed my Procfile to only run one dyno:

web: npm start& sh -c 'cd ./Python/ && export PYTHONPATH=. && python other.py'

Now I can make my call to 127.0.0.1:2001 without any problems.
