`api.authentication_invalid`

API authentication is not a list of declared sign-in methods.

Area 7, HTTP; not declinable; the next step is usually the agent's.

An API lists the sign-in methods it accepts, each one authentication.jadpo declares (area 8):

example

application {    apis: {        main: {            prefix: /v1            authentication: [AuthenticationMethod.browser_session]        }    }}

jadpo checkcheck failed: 1 error, 1 file

error API main accepts browser_session, which isn't declared

--> app.jadpo:5:30

  |5 |             authentication: [AuthenticationMethod.browser_session]  |                              ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ not declared

reason: An API accepts only the ways to sign in the application declares; authentication.jadpo declares no way to sign in yet.
next: List the methods the API accepts, each one authentication.jadpo declares (agent)
rule: api.authentication_invalid
