.catch((err) => console.error(
  'Error: [%s] %s: %s',
  err.name,
  err.message,
  err.errors()[0].description,
))
Date("2018-06-06")
result = client.query(
  q.to_date("2018-06-06")
)
print(result)
2018-06-06
result, err := client.Query(
	f.ToDate("2018-06-06"))

if err != nil {
	fmt.Fprintln(os.Stderr, err)
} else {
	fmt.Println(result)
}
