HTTP Status Codes

HTTP 102 Processing

102 Processing

The server has received the request and is processing it, but no final response is available yet.

102 Processinggeneral

Observed message

102 Processing

Why it happens

  • The request triggered an informational response during negotiation, upload, or long-running processing.
  • The client and server exchanged interim response details before the final status code was sent.
  • A proxy, framework, or client surfaced the interim status directly for logging or debugging.

How to fix it

  1. Check the final response status as well as the interim status to understand the full request outcome.
  2. Review upload, streaming, or protocol negotiation behavior if the informational response is unexpected.
  3. Confirm whether any client library, proxy, or framework is surfacing interim responses in UI or logs.
