[bug]: create-next-app errors are replaced with generic error message

[Yonom]

Describe the bug

When triggering a new project via the shadcn CLI (running it in a folder without package.json), the create-next-app CLI errors are not displayed to the user (e.g. project name can only contain lower case letters)

Affected component/components

npx shadcn

How to reproduce

npx create-next-app AAAA

Could not create a project called "AAAA" because of npm naming restrictions:

• name can no longer contain capital letters

npx shadcn@latest add button

✔ The path / does not contain a package.json file. Would you like to start a new Next.js project? … yes
✔ What is your project named? … AAAA
