DTK0050: Dock Already Registered

Message

Dock with id "{id}" is already registered

Cause

ctx.docks.register(view) is called twice with the same id. The kit's DocksHost enforces unique ids so each dock entry has a stable handle.

Example

ctx.docks.register({ id: 'my-plugin:main', title: 'My Plugin', type: 'iframe', url: '/__foo/' })
ctx.docks.register({ id: 'my-plugin:main', title: 'My Plugin (again)', type: 'iframe', url: '/__foo/' })
// Throws DTK0050

Fix

Pick a different id, or call ctx.docks.update(...) to mutate the existing entry. Pass force: true as the second arg to register to intentionally replace the existing entry — this is what the auto-derived dock from createPluginFromDevframe uses internally.

• packages/kit/src/node/host-docks.ts — DevToolsDockHost.register throws DTK0050 when an id is already in views and force was not set.
