# X_CASSETTE_UNUSED

## Means

a cassette entry was never replayed

## Typical cause

the code under test no longer makes a request the cassette recorded, so the recording describes a run that does not happen

## Fix

`ULTIMATE_CASSETTE=record bun test <file>` — re-record — or delete the entries meta.unused names from the cassette file
