Trying to add persistence profile in existing virtual server

I am trying to add persistence profile in an existing Virtual server but not able to do so. It is showing some errors.

Add-PSSnapIn iControlSnapIn
Initialize-F5.iControl -Hostname "hostname" -Username "username" -Password "password"

$virtual_name = New-Object iControl.CommonVirtualServerDefinition
$virtual_name.name="app035"
$virtual_name.address="0.0.0.0"
$virtual_name.port=80
$vir_server = New-Object iControl.LocalLBVirtualServerVirtualServerPersistence
$vir_server.default_profile = $false
$vir_server.profile_name="cookie"

(Get-F5.iControl).LocalLBVirtualServer.add_persistence_profile($virtual_name,$vir_server)

Error this time is -

Exception calling "add_persistence_profile" with "2" argument(s): "Exception caught in 
LocalLB::urn:iControl:LocalLB/VirtualServer::add_persistence_profile()

    I do not know PowerShell, but from the error message, 

    The requested virtual server 
(/Common/iControl.CommonVirtualServerDefinition) was not found
    , I would say that the virtual does not exist. Check if exists.

    If that's not the case, I suspect the data format of the persistence profile(s). It must be given in array (

    []
    ). For example, to perform the task equivalent to the following tmsh command (adding 
    cookie
    persistence profile to the virtual 
    vs
    😞

    tmsh modify ltm virtual vs persist replace-all-with { cookie }

    You need to PATCH the 

    /mgmt/tm/ltm/virtual/vs
    endpoint with the data 
    {"persist":[ {"name":"cookie"} ]}
    .

    A curl call looks like this:

    curl -sku : https:///mgmt/tm/ltm/virtual/vs \
  -X PATCH -H "Content-type: application/json" \
  -d '{"persist":[ {"name":"cookie"} ]}'
