When using otel, the logc print log will be deformed

[Cairry]

Describe the bug
My service uses otel. When printing logs through logc, the log format is deformed. I understand that traceid and spanid should be inside json, not in the outer layer.

1. The code is

   logc.Infow(context.Background(), "CallBack request successfully.", logc.Field("reqId", params.Spec.ReqId))

2. The error is

   trace_id=dfac27371ea9966e8da25340b5924dc7 span_id=6fe11f97dfa23e52{"@timestamp":"2025-08-26T13:49:09.815+08:00","caller":"task/task.go:88","content":"CallBack request successfully.","level":"info","reqId":"1960191682599202817","span":"6fe11f97dfa23e52","trace":"dfac27371ea9966e8da25340b5924dc7"}
   

Expected behavior

{"@timestamp":"2025-08-26T13:49:09.815+08:00","caller":"task/task.go:88","content":"CallBack request successfully.","level":"info","reqId":"1960191682599202817","span":"6fe11f97dfa23e52","trace":"dfac27371ea9966e8da25340b5924dc7"}
