Save array data in Dgraph

Hi i want save a array data in dgraph .
but when i save my data , data save null .

	Experiences: []Experience{
			ID:          "5e24971bad4ff71826010d74",
			Place:       "test",
			JobRole:     "test",
			Description: "test",

this is my data example.
how i can save this data in dgraph for a node ?

Could you look what the corresponding JSON looks like for the mutation? If you could share that, it will be really easy to figure out what the issue is.
