Trying to create namedacl - returns error with the access_list payload format

[#1]

I get this error for the access_list format. I have tried different things . But I am unable to GET access_list or POST it. Appreciate any help on this. 

RESPONSE :

{

"Error": "AdmConProtoError: Missing struct type in access_list.",

"code": "Client.Ibap.Proto",

"text": "Missing struct type in access_list."

}

POST : https://gridname/wapi/v2.13.1/namedacl
{

"access_list" : [

{

"address": "22.22.22.22/24",

},

}

]
