HTTP 102 Processing vs 409 Conflict
HTTP 102 (Processing) is a 1xx Informational response, while 409 (Conflict) is a 4xx Client Error response. 102 indicates that the server has received and is processing the request, but no response is available yet. Prevents the client from timing out. In contrast, 409 means that the request conflicts with the current state of the server. Often due to concurrent modification or business rule violations.
