Heroku to railway, plotly-dash, deployment crash
I am following the migrating guide / blog to host my python plotly-dash interface on railway. This setup worked fine on heroku but deployment here is failing and it does not make a lot of sense to me.
Procfile: web: gunicorn app:server
Requirements.txt has all the necessary python modules and worked fine for heroku
Script is called app.py (Running at https://signs-of-2b2t.herokuapp.com/)
Build logs: look good
Deploy logs: posted below
Thanks in advance for any help

Bumping here: we are noticing Pandas are giving us an issue on Nixpacks. You can attempt to switch build solutions on the platform.
deprecated heroku build pack works...

Ye
You can use that, we're just phasing them out
pandas is quite an important package lol
i hope you get it figured out some time
Definitely. Checking to reproduce it now
But I mean this is why we've only deprecated it not fully removed it 🙂
Works for me on this repo
Just cloned it
yes i only ever ran it from the site
The site uses that exact same distribution
Nothing different
nix packs build ?
Yep
i tried it two hours ago lol
ok ill send you the logs
Very weird.....
lol i cant copy the whole thing
ProjectID would suffice
And it's this exact same repo? Verbatim?

wtf
yes im just doing a brand new deploy from that repo
Can you try redeploying again. I was just able to successfully deploy on Railway using the latest (0.3.12) version of Nixpacks
yea idk how this isnt working lol
I wonder if it's now cached a bunk version
Can you delete the project and recreate it?
Or just the service
i mean i just created a new project
o
wtf

I've just discovered what the issue is. Can you remove the start command on the service settings page. It slightly changes the behaviour (we will be fixing this on Railway)
well youre right it works now
on nix packs
thanks for the help guys
you can probably close this one
