add user agent, src ip and dataset name to the error

Summary by CodeRabbit

  • Bug Fixes
    • Standardized invalid API-key responses with a clear “Invalid API key” message.
    • Improved unauthorized-access diagnostics by recording relevant request context, including source address, endpoint, client details, dataset, and requested tenant when available.
    • Added consistent fallback values when request metadata is unavailable.
    • Improved source-address detection during data ingestion, including support for peer-address details and an “unknown” fallback.

Walkthrough

The HTTP handlers improve invalid API-key diagnostics. The middleware logs request metadata and returns a fixed error message. Ingest metadata extraction uses the request peer address with an "unknown" fallback.

Layer / File(s) Summary
Enrich invalid API-key errors
src/handlers/http/middleware.rs, src/handlers/http/modal/utils/ingest_utils.rs
The middleware logs source IP, endpoint, user agent, dataset, and requested tenant fields. It returns "Invalid API key". Ingest metadata uses peer_addr() and falls back to "unknown". Tests cover both source IP cases.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 701c5

The change can report a proxy’s address instead of the real client IP for requests passing through trusted proxies, leading to incorrect request metadata. Merge should wait for correct real-IP handling or explicit owner acceptance with a focused test.

Poem

A rabbit checks the API gate,
And logs the clues when keys are late.
The message stays brief and clear:
"Invalid API key" is all you hear.
If peer data hides from sight,
"unknown" keeps the record right.

substituting DEFAULT_TENANT when tenant_id is absent; record an explicit unknown
value under requested_tenant, or omit the field entirely. Preserve the resolved
tenant value when available and do not treat an incoming tenant header as
authoritative without an authenticated tenant.
- Around line 218-225: Update the invalid API-key handling around error_message
and the tracing::warn! call so the 401 ErrorUnauthorized body contains only a
generic authentication failure, while source IP, user agent, dataset, and tenant
remain available only in structured logs. Change the tenant log field to
preserve an absent tenant value instead of substituting DEFAULT_TENANT.

⚠️ Unverified finding
Sandbox verification was unavailable.

Preserve the real client IP behind trusted proxies.

req.peer_addr() returns the immediate socket peer. If requests pass through a reverse proxy, SOURCE_IP_KEY will contain the proxy IP instead of the client IP. This changes the previous connection-info real-IP behavior and can make ingested metadata incorrect.

Keep the trusted real-IP resolution, or define a trusted-proxy policy that uses forwarded client IPs and falls back to peer_addr() only when appropriate. Add a test with different forwarded and peer addresses.
