HTTP 424 Failed Dependency vs 429 Too Many Requests
Both HTTP 424 (Failed Dependency) and 429 (Too Many Requests) belong to the 4xx Client Error category. 424 indicates that the request failed because it depended on another request that failed (WebDAV). Meanwhile, 429 means that the user has sent too many requests in a given time (rate limiting). The response should include a Retry-After header.
