# X_NOTIFY_CHANNELS_EMPTY

## Means

the notifier declares no channels

## Typical cause

an empty `deliver: []`. Refused where it is written: a notifier with no channel resolves its recipients on every run and delivers to nobody

## Fix

add at least one entry to `deliver: []` on `notifier("<name>")` — `inAppChannel()` is the one with no external driver
