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.
