# X_NOTIFY_DIGEST_UNSUPPORTED

## Means

a digest window is declared on a bulk channel

## Typical cause

`digest:` beside a `bulkChannel()`. Refused where it is written: a bulk send has one payload for the whole audience and a window coalesces PER RECIPIENT, so the two have no shared meaning — and inventing one would be this package deciding whose events get grouped

## Fix

drop `digest` from that entry and give it a `wait` instead, or deliver it through `deliveryChannel('<name>', …)` one recipient at a time
