# X_TEST_ISLAND_STATES_UNKNOWN

## Means

no island state manifest answers to that name

## Typical cause

`findIslandStates(all, name)` resolved nothing. A typo and an island whose states were never declared are one symptom and two different edits, so `cause` lists every valid name

## Fix

name one of the islands the cause lists — or, when none is listed, declare one beside the island: `export const states = defineIslandStates({ island: 'apps/web/app/settings/settings.island.tsx', states: [] })`
