`shadcn` CLI fails when adding component from external registry URL — requests `.../r/styles//button.json` (empty `style`)

[rodrigoogalde]

When I try to add a component from an external registry URL, the CLI errors out while fetching a dependency from the official registry. It builds a URL with an empty style segment (styles//button.json), which suggests the CLI isn’t reading style from components.json for this code path.

Command

npx shadcn@latest add https://ui.bazza.dev/r/filters

Output

Checking registry.

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//button.json was not found.
It may not exist at the registry. Please make sure it is a valid component.
