HTTP 102 Processing vs 422 Unprocessable Content
HTTP 102 (Processing) is a 1xx Informational response, while 422 (Unprocessable Content) 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, 422 means that the server understands the content type and syntax, but was unable to process the contained instructions. Common in API validation errors.
