method.field_path_unresolved

A path names a field its concept does not have


Type	`https://mthds.ai/errors/method.field_path_unresolved`
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 binding's from, a construct's from or a template's field read walks past what the declared structures hold, such as a segment naming no field, or one following a native that holds its value in a single field.

What to do

Compare the path with the concepts' structures, using params.available_fields at the failing segment, and correct it, or bind the field first and walk on from the bound value.

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`	Correct the path '`{path}`' so that it names fields its concepts hold, then validate the method again.
Any other reader	`contact_owner`	Ask the method's owner to correct the path '`{path}`' in pipe '`{pipe}`'.

Detail

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

In pipe '{pipe}', the path '{path}' cannot follow '{segment}', which is not a field of the value before it.

Parameters

Every parameter is present on every occurrence of the code.

Name	Type	Description
`pipe`	`identifier`	The pipe holding the path.
`path`	`identifier`	The path.
`segment`	`identifier`	The segment the walk cannot follow.
`available_fields`	list of `identifier`	The fields the structure holds where the walk stops, empty when the walk stops at a leaf.
