454-460: 🗄️ Data Integrity & Integration | 🔵 Trivial | 💤 Low valueOperator headers can override
Content-TypeandContent-Encoding.The loop applies
cfg.Headersafter the two protocol headers. A configured header namedContent-TypeorContent-Encodingreplaces the value this publisher set. The collector then rejects every batch, or fails to inflate a gzip body. Set the protocol headers after the loop so they always win.♻️ Proposed fix
- req.Header.Set("Content-Type", "application/json") - if o.gzip { - req.Header.Set("Content-Encoding", "gzip") - } for k, v := range o.cfg.Headers { req.Header.Set(k, v) } + // Set last so a configured header cannot override the wire format. + req.Header.Set("Content-Type", "application/json") + if o.gzip { + req.Header.Set("Content-Encoding", "gzip") + }🤖 Prompt for AI Agents

Inline comments:
In `@gateway/gateway-runtime/policy-engine/internal/analytics/publishers/otel.go`:
- Around line 163-166: Update validateOTelPublisherConfig around the existing
plaintext HTTP warning to reject non-loopback http:// endpoints when cfg.Headers
is non-empty, preventing post from sending credentials over plaintext; retain
the current warning-only behavior when no headers are configured.
- Around line 1104-1112: Update the packaged collector configuration’s
service.pipelines section to add a logs pipeline that uses the existing OTLP
receiver and intended exporter, alongside the traces pipeline. Ensure records
sent to /v1/logs are processed without changing the otelLogRecord encoding.
- Around line 889-891: Update appendAIAttributes to emit gen_ai.operation.name
only when the event API type is LlmProvider or LlmProxy; retain the existing
otelGenAIOperationName mapping and attribute behavior for those event types,
while suppressing it for all other routes and API types.
In `@gateway/gateway-runtime/policy-engine/internal/config/config.go`:
- Around line 1570-1575: Update the endpoint validation around url.Parse in the
OTel configuration flow to reject any URL with non-nil userinfo (u.User), before
accepting the endpoint scheme. Preserve credential-free HTTP and HTTPS
endpoints, and direct users to provide credentials through Headers instead.
- Around line 1574-1575: The validateOTelPublisherConfig validation currently
permits plaintext HTTP OTLP endpoints without explicit opt-in. Require
allow_insecure_transport for HTTP endpoints (or otherwise reject HTTP by
default), update the packaged OTel default to use HTTPS or the opt-in setting,
and adjust the related validation and configuration tests accordingly.
- Around line 1648-1649: Before each client certificate/key load in the OTel TLS
configuration paths, validate that cfg.KeyFile is a regular file and has no
group or other permission bits; return an error and stop startup when validation
fails. Apply this consistently around every tls.LoadX509KeyPair call, including
the shown config flow, while preserving the existing certificate-loading
behavior.
In `@gateway/system-policies/analytics/analytics.go`:
- Around line 430-433: Update the capability assignment logic around
deriveMCPCapability so CapabilityName is populated only for explicit
McpCapabilityTool or McpCapabilityPrompt values; retain ResourceUri handling for
McpCapabilityResource and leave both target fields empty for unrecognized
capabilities. Add a regression case covering an unknown method with params.name.
- Line 424: Update the JSON-RPC payload decoding and ID assignment near
props.JsonRpcID so numeric IDs retain their exact representation: configure the
decoder with UseNumber, handle json.Number values, and store their String()
result instead of converting through float64/int64. Add regression tests
covering both a large integer ID and a non-integer ID.
