route.input_not_input

Route input is not an Input type.

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

A route accepts only an Input:

example
type Memo = Text {    max_length: 200}type MemoId = Uuid {}type AddMemo = Input {    text: Memo}type MemoView = Output {    text: Memo}action add_memo(input: AddMemo) -> MemoView {    return MemoView {        text: input.text    }}routes Memos {    prefix: /memos    POST / {        input: MemoView        output: MemoView        run: add_memo(input)    }}

error MemoView isn't an Input

--> main.jadpo:25:16

   |25 |         input: MemoView   |                ^^^^^^^^ not an `Input`
reason
A route accepts only an Input type (area 2): the only objects that may leave fields out or fill them by default, and the ones a request's fields are checked against.
next
Declare type <Name> = Input { ... } and take it here (agent)
