method.not_runnable

The method still holds pipe signatures


Type	`https://mthds.ai/errors/method.not_runnable`
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 run reached a pipe that is still declared as a signature, with no implementation. Validation reports such pipes as a runnability fact, pending_signatures, rather than as a fault.

What to do

Implement each pipe that pending_signatures lists on the /validate verdict before running the method.

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`	Implement the signature '`{pipe}`', then run the method again.
Any other reader	`contact_owner`	Ask the method's owner to implement the signature '`{pipe}`'.
