pipe.output_invalid

A pipe's output does not fit its concept


Type	`https://mthds.ai/errors/pipe.output_invalid`
Family	`pipe`: A pipe failing at run time because of what the method does.
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

What a pipe produced fails its declared concept's structure, such as a required field that is missing or a value of the wrong type.

What to do

Compare the pipe's output with the concept's structure at params.fields, then change the pipe, its prompt or its function, or the concept, so that they agree.

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`	Make pipe '`{pipe}`' produce an output that fits '`{output_concept}`', or loosen the concept, then run the method again.
Any other reader	`contact_owner`	Ask the method's owner to make pipe '`{pipe}`' produce an output that fits its concept.
