Configure virtual server with pool using tmsh

I am using iApps to create all my objects, so I can easily edit them, duplicate them, etc.

Most of my iApp code is tmsh::create { } with all the parameters within to create the object. However, the most recent stumper is getting a pool attached to the virtual server.

With the code below:

tmsh::create ltm virtual /Common/tableau_test_443_vs {
    destination /Common/128.83.124.23:443
    ip-protocol tcp
    mask 255.255.255.255
    profiles replace-all-with {
        /Common/serverssl {
            context serverside
        }
        /Common/std_https_prof { }
        /Common/tableau_test_cert_prof {
            context clientside
        }
        /Common/tcp { }
    }
    source 0.0.0.0/0
    source-address-translation {
        type automap
    }
    translate-address enabled
    translate-port enabled
    pool tableau_test_443_pool
}

I get the following error:

01020036:3: The requested pool (tableau_test_443_pool) was not found.

The pool exists and to be sure I spelled right, I copied and pasted the name. What is the syntax for adding a pool? Am I missing something?
