Hello - i deployed several apps with Railway using only the Railway templates, and it worked but my i am having hard time with my current project -- Serving Flask app "main" (lazy loading) Environment: production WARNING: This is a development server. Do not use it in a production deployment. Use a production WSGI server instead. Debug mode: off

you said you used railway templates without issues, so the difference between those templates and your current project would be the templates used gunicorn in the start command

i already have the procfile with this "web: gunicorn main:app" so not sure if that is enough

Brody•13mo ago

well that's usually enough yes does the procfile have a capital P?

sas70•13mo ago

the image is build with no issues but when i run the app it fails starting No

Brody•13mo ago

needs a capital P

sas70•13mo ago

https://pdf2t2c-production.up.railway.app/ the only change made is the capital P for procfile

Brody•13mo ago

what are you doing to cause the timeout? calling some endpoint?

sas70•13mo ago

calling the ADOBE API services and it takes around 10 sec to respond

Brody•13mo ago

[CRITICAL] WORKER TIMEOUT means the request took longer than 30 seconds, 30 seconds is gunicorns default timeout

sas70•13mo ago

when i ran the app using localhost, it takes 10-15 sec only I just ran it and it took 9 sec locally

Brody•13mo ago

looks like you have a code issue on your hands maybe something you are doing in code during that enpoint request is silently failing and locking up the request causing it to time out

sas70•13mo ago

ok then let me have another look tomorrow and get back to you

Brody•13mo ago

add proper error handling, and time telemetry throughout your code to see where the hold up is

sas70•13mo ago

Thank you for the great support. At least the app is launching and passed the build and deployment stages 🙂 thank you.

Brody•13mo ago

no problem 🙂

sas70•13mo ago

Brody - The endpoint is up and running. I had an issue with an API key. So wll is good now. Thank you again for the help 🙂

Brody•13mo ago

glad it was something simple! make sure you add proper error handling so this doesn't happen again!
