Source: https://docs.vlayers.ai/errors/no_sender

- HTTP status: 409
- Retry: No: fix the request first
- details: `channel`, and `nextStep: "mailbox_create"` for email.

## What happened

Nothing to send from on this channel.

## Why

The send left out `from`, and the workspace (or the key's Line) has no sender on this channel: no number, Binding or mailbox to send from.

## How to fix it

Connect a sender for the channel in the dashboard (for email, create a mailbox), or name one in `from`.
