The same commit is first failing and then building but I still see a warning icon on the canvas card.
How do I upgrade nodejs 18x. Locally I'm using node 23x. There is no railway config file in my git repo. Should I add one and where do I fetch a sample config I can mirror?
How is the same build failing and then running? It's the same commit.
```

for railpack will automatically set based on these files https://railpack.com/languages/node. maybe you can check these files. the default is 22.
and for nixpack the default is 18https://nixpacks.com/docs/providers/node
my suggestion is always set it atleast at every project's package.json manually, it would be good not only for deployment but also for your team version uniformity.

Does this page support markdown code blocks?

Assuming you're using the nixpacks builder (based on the logs it appears that you are) you should be able to set the node version with an environment variable. NIXPACKS_NODE_VERSION = 23
setting that and restarting should do the trick. You can also try changing the builder to Railpack. Nixpacks is EOL as far as I know

If you don't set anything doesn't railpack automatically kick in? I also never set my own nixpack so unclear how this config is being set.
