Quantiles in prometheus.SummaryOpts in golang shows as undefined while accessing

[arjunbakshi245]

A Summary metric in prometheus with quantiles. But while running a gatherer on all my metrics the Quantiles field for the Summary says
m.GetSummary().Quantiles undefined (type *io_prometheus_client.MetricFamily has no field or method Quantiles)
Need help to access the length of the Quantiles field in the my custom gatherer. Not sure if my access technique is correct.

for _, mf := range mfs{
        if mf.GetType() == dto.MetricType_SUMMARY{
                for _, m := range mf.GetMetric() {
	             fmt.Println(m.GetSummary().Objectives) // Quantiles also give same error
                } 
       }
}

m.GetSummary().Quantile
Worked.
