What it means

A template or a step reads a variable that the pipe's inputs do not declare.

What to do

Add each of params.variables to the pipe's inputs with its concept, or correct the name the template reads.

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`	Declare what pipe '`{pipe}`' reads in its inputs, or stop reading it, then validate the method again.
Any other reader	`contact_owner`	Ask the method's owner to declare the inputs pipe '`{pipe}`' reads.

Detail

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

Pipe '{pipe}' reads names its inputs do not declare: {variables}.

Parameters

Every parameter is present on every occurrence of the code.

Name	Type	Description
`pipe`	`identifier`	The pipe at fault.
`variables`	list of `identifier`	The names it reads and does not declare.
