I don’t see @remix-run/dev in your devDependencies. However, I came across Remix’s changelog referring to this – it looks like a fix was made: changelog#v241.
“avoid issues where
@remix-run/devcould be inadvertently required in your server’s production dependencies”
Could you make sure you’re using @remix-run/dev@2.4.1 or greater in your devDependencies? Otherwise, without seeing the codebase itself, it will be quite challenging to determine what’s causing this error to crop up during deployment.
