receiving.invalid: A queue in receiving: doesn't say how its messages are read

A queue in receiving: doesn't say how its messages are read.

Area 12, Background work; not declinable; the next step is usually the agent's.

A queue in receiving: is read through a connection to a package that provides receiving or to Cloudflare Queues (driver: Driver.cloudflare_queues), says where each message's id is with id_at:, and lists the events its messages may be; with more than one event, type_at: says where each message's type is. A database's connection reads no queue:

example

application {    connections: {        main: {            driver: Driver.postgres        }    }    receiving: {        main: {            id_at: "message_id"            events: []        }    }}

error main isn't a connection a queue is read through

--> app.jadpo:8:9

  |8 |         main: {  |         ^^^^ not a queue's connection

reason: A queue in receiving: is a connection to a package that provides receiving, or one with driver: Driver.cloudflare_queues; it gives id_at:, where each message's id is in its body, events:, the events its messages may be, and type_at:, where each message's type is, unless it lists one event.
next: Add main to connections: with the package: its queue is read through, or driver: Driver.cloudflare_queues, or name one that is (agent)
