When attempting to add the v0 component https://v0.dev/chat/b/b_MDsFl9sNbn4 using npx shadcn@latest add, the command fails with a 404 error:
Something went wrong. Please check the error below for more details. If the problem persists, please open an issue on GitHub.
The component at https://ui.shadcn.com/r/styles/new-york-v4/date-picker.json was not found. It may not exist at the registry. Please make sure it is a valid component.
This occurs because the v0 component appears to have an invalid dependency declared (pointing to date-picker.json), which doesn't exist in the official shadcn/ui registry, as the Date Picker is meant to be composed manually.
Expected behavior: Ideally, the shadcn add command should either: a) Successfully install the v0 component if its dependencies are valid and exist.
b) Provide a more informative error indicating that a dependency is pointing to a non-existent registry component.
c) Potentially handle the composition automatically if the intent is clear.
