Getting error while adding the user

I have created a user and under that I have one more user that user added 7 device till then it's ok but now when I am adding the 8th one getting the issue.

Administrator access required-SecurityException(PermissionsService: 79<*: 189<UserResource: 103<...<OverrideFilter: 49<...)

My device limit = -1
user limit = -1

This is my payload:

{
    "name": "Yuvraj Jwala",
    "email": "yuvraj...",
    "password": "9876545678987",
    "phone": "8789229147",
    "readonly": false,
    "disabled": false,
    "deviceReadonly": false,
    "limitCommands": false,
    "fixedEmail": false,
    "expirationTime": "2027-03-28",
    "attributes": {
        "devicePoint": 0,
        "userPoint": 0,
        "userType": "normal",
        "is_mobilized": true
    }
}

You forgot to mention the version.
