`configuration.url_type`

Connection address is not a setting of the type its driver needs.

Area 10, Configuration; not declinable; the next step is usually the agent's.

example

config {    cache_url: RedisUrl}

example

application {    connections: {        main: {            driver: Driver.postgres            url: config.cache_url        }    }}

jadpo checkcheck failed: 1 error, 2 files

error main's address must be a PostgresUrl setting

--> app.jadpo:5:18

  |5 |             url: config.cache_url  |                  ^^^^^^^^^^^^^^^^ `cache_url` is `RedisUrl`

reason: A connection opened with driver: Driver.postgres takes an address of its own type, which checks the scheme and is always secret; config.cache_url is RedisUrl.
next: Declare <name>: PostgresUrl in config.jadpo, and write url: config.<name> (agent)
rule: configuration.url_type
