method.wiring_invalid

A pipe's wiring does not give it what it reads


Type	`https://mthds.ai/errors/method.wiring_invalid`
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 reads a variable or an attribute in a shape its wiring does not give it, or a controller's steps do not connect.

What to do

Follow the variable from the step that stores it to the pipe that reads it, and make the stored concept and multiplicity match what the reader declares.

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`	Wire pipe '`{pipe}`' so that '`{variable_path}`' reaches it in the shape it reads, then validate the method again.
Any other reader	`contact_owner`	Ask the method's owner to fix the wiring of pipe '`{pipe}`'.

Detail

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

Pipe '{pipe}' reads '{variable_path}' in a shape its wiring does not give it ({finding}).

Parameters

Every parameter is present on every occurrence of the code.

Name	Type	Description
`pipe`	`identifier`	The pipe at fault.
`variable_path`	`identifier`	The variable or the attribute path the pipe reads.
`finding`	`caller_text`	How the wiring differs from what the pipe reads.
