# X_TEST_ISLAND_STATE_ID_INVALID

## Means

an island state id is not slug-shaped

## Typical cause

the id becomes the screenshot FILENAME stem, so a space, a slash or a capital is either an unguessable path or a path outside the shot directory

## Fix

write the id the cause suggests: `id: 'over-quota'` — lowercase letters, digits and single dashes
