HTTP 102 Processing vs 502 Bad Gateway
HTTP 102 (Processing) is a 1xx Informational response, while 502 (Bad Gateway) is a 5xx Server 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, 502 means that the server, acting as a gateway or proxy, received an invalid response from the upstream server.
