description: A path, query or header parameter is malformed or repeated.

**HTTP status:** `400`.

A request parameter is not in the form this operation expects, was supplied more than once, or could not be read. The message names the parameter.

## Troubleshooting

- Compare the named parameter against its schema in GET /v1/openapi.yaml.
