input.invalid

An input does not fit its concept's structure


Type	`https://mthds.ai/errors/input.invalid`
Family	`input`: A run's inputs.
Domain	`input`: the caller acts, by changing the request or its inputs
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

An input's value fails its concept's structure, such as a required field that is missing or a value of the wrong type, or breaks the rules of its content type. The problem names the field and never what the check found in the value, which a validator's message can quote and which is the content of the run's input.

What to do

Compare the input with its concept's structure at the field params.field names, and correct the value.

Next steps

A problem carries the step aimed at whoever reads it: the first when its reader is the domain's actor, the caller, and the second for any other reader.

Reader	Kind	Detail
The domain's actor	`change_input`	Correct the field '`{field}`' of the input '`{input}`', then send the request again.
Any other reader	`change_input`	Pass this to the caller, who must correct the field '`{field}`' of the input '`{input}`'.
