How to add Json array into dataframe

Couchbase Server
,
1

[{
“Name” :“Test”
“Salary”:2000
“Department”:“Maths”
},
{
“Name” :“Test”
“Salary”:2000
“Department”:“Maths”
}
]

I want to convert this json array into dataframe with the couchbase connector . Also this json array is not fixed , so i cannot add the schema mannualy and also i cannot add the key to the array.
Have tried this code after doing indexing on the bucket and putting all the mandatory configurations such as username , password ,serverIp etc.

val jsonArray = sql.read.couchbase

But resulted dataframe only contains META_ID. It is unable to read the schema of json array.

What to do ?
