Precondition Failed

The 412 Precondition Failed HTTP status code is returned when one or more conditions specified in an HTTP request headers are not met on the server. These headers, known as preconditions, allow a client to ensure that specific conditions are met before making a request or processing the response. The 412 code indicates that the server understands the preconditions set by the client but cannot fulfill them due to an underlying issue or conflict with the current state of the resource on the server.
