If else condition in Rest CreateAccount JSON

[RizvanaShaik]

Hi Team,

while creating an account for application we are using Createaccount JSON as follows where we want the sid attribute to be populated if and only if the account name starts with 'S'

however , it is not working please specify if am missing anything syntax wise 

below is the create account JSON 

{
"accountIdPath": "accountName",
"dateFormat": "yyyy-MM-dd'T'HH:mm:ssXXX",
"call": [
{
"name": "call1",
"connection": "acctAuth",
"showResponse": false,
"url": "<URL here>/v2/users",
"httpMethod": "POST",
"httpParams": "{ \"eid\": \"${user.username}\", \"sid\": \"${arsTasks.accountName like 's%'?arsTasks.accountName:'null'||''}}\", \"name\":\"${user.firstname+' '+user.lastname}\",\"firstName\": \"${user.firstname}\", \"lastName\":\"${user.lastname}\", \"email\": \"${user.email}\",\"active\": \"true\",\"role\":\"View Only\"}",
"httpHeaders": {
"Authorization": "${access_token}"
},
"httpContentType": "application/json",
"successResponses": {
"statusCode": [
201,
200
]
},
"unsuccessResponses": {
"statusCode": [
400,
401,
403,
404
]
}
}
]
