shopify-cli migration npm run dev error

[jameshagood]

when i run npm run dev, everything appears to work fine and at the end it says

Abort [Error]: Command failed with exit code 1: npm run --prefix ../.. dev

 error ──────────────────────────────────────────────────────────────────────╮
│                                                                              │

has anybody else had this error?

I am also having this error when I try to run `shopify app dev` command with railway cli.
