The missing trace data in two Go services was caused by the GoFrame tracing middleware recording the gzip‑compressed /metrics response body as a UTF‑8 string, which the OpenTelemetry exporter rejected as invalid UTF‑8; disabling Prometheus compression or decompressing the body before logging resolves the issue.
