HTTP 424 Failed Dependency is a WebDAV extension (RFC 4918) indicating the request failed because it depended on another request that also failed. This occurs in batch operations where an action on one resource requires a prior action on another resource to succeed. If the dependency fails, all dependent operations return 424. Think of it as cascading failure reporting in a multi-step operation.
Response includes the status code, standard headers (including Content-Type), and a small diagnostic JSON body describing the request and returned status.
