--- set: 4 code: 424 title: Failed Dependency references: "Rails HTTP Status Symbol": "failed_dependency" --- The 424 (Failed Dependency) status code means that the method could not be performed on the resource because the requested action depended on another action and that action failed. For example, if a command in a PROPPATCH method fails, then, at minimum, the rest of the commands will also fail with 424 (Failed Dependency). Source: [RFC4918 Section 11.4][1] [1]:
