Family	`method`: The method as written, the validation vocabulary included.
Domain	`method`: the method's author acts, by changing the method
Retry	`no`: repeating the operation fails the same way
HTTP status	`422`
Raised as	a problem document, sent as the body of an HTTP response or kept in a run's record

What it means

A pipe names no type, an unknown one, or one the language has retired.

What to do

Set the pipe's type to one of the operators or controllers the language defines, and give it that type's fields.

Next steps

A problem carries the step aimed at whoever reads it: the first when its reader is the domain's actor, the method's author, and the second for any other reader.

Reader	Kind	Detail
The domain's actor	`change_method`	Give pipe '`{pipe}`' one of the language's pipe types, then validate the method again.
Any other reader	`contact_owner`	Ask the method's owner to give pipe '`{pipe}`' a valid type.

Detail

The problem's detail is written from this template, filled with the occurrence's parameters:

Pipe '{pipe}' has no usable type (reason: {reason}).

Parameters

A parameter is present on every occurrence of the code unless it is marked optional, and one marked operator-only reaches only whoever runs the runtime, never a caller.

Name	Type	Description
`pipe`	`identifier`	The pipe at fault.
`reason`	one of `missing`, `unknown`, `retired`	Whether the type is missing, unknown or retired.
`pipe_type`	`caller_text` (optional)	The type as the method writes it, when it writes one.
