Server with same base url already exists, ${server.baseUrl}

Error message

Server with same base url already exists, ${server.baseUrl}

What it means

A uniqueness guard in the server-list store: addServer checks the persisted serverList for an existing entry whose baseUrl equals the new server's baseUrl. It fires on an attempt to register a custom server whose base URL was already added, because the list is keyed by base URL; the interpolated value is the duplicated base URL.

Solutions

1. The server is already in the list; select the existing entry instead.
2. Remove the existing entry first if you intend to re-add it.

When it happens

Trigger: Thrown in ServerListStore.addServer when a stored server already has the same baseUrl as the one being added.

Common situations: Occurs when a user tries to add a self-hosted server that is already in the list. Use the existing entry instead of adding a duplicate.
