route.argument_invalid

Route passes something other than a placeholder, the input or their fields.

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

A route passes its placeholders, input and their fields; anything worked out goes in what it runs:

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 / {        output: MemoView        run: add_memo(            AddMemo {                text: "Hello"            }        )    }}
text
