Function MarshalToJSONV1

pkg/tempopb/trace_utils.go:14–22

It marshal a Trace to an OTEL compatible JSON. Historically, our Trace proto message used `batches` to define the array of resourses spans. To be OTEL compatible we renamed it to `resourcesSpans`. To be backward compatible, this function use jsonpb to marshal the Trace to an OTEL compatible JSON and

(t *Trace)

// To be backward compatible, this function use jsonpb to marshal the Trace to an OTEL compatible JSON
// and then replace the first occurrence of `resourceSpan` by `batches`.
func MarshalToJSONV1(t *Trace) ([]byte, error) {
	marshaler := &jsonpb.Marshaler{}
	jsonStr, err := marshaler.MarshalToString(t)
	if err != nil {
		return nil, err
	}
	jsonStr = strings.Replace(jsonStr, `"resourceSpans":`, `"batches":`, 1)
	return []byte(jsonStr), nil
}
