Getting error while using http post 'manual captcha dialog'..please advise.

[Sanjeev 46]

Guys?

 

I am  getting an  'object reference not set to an instance of an object ' error message when I try to run the below code..

Please help me with some workaround. 

 

[i am using the latest update of the Http post plugin - 2.4.9]

 

Thanks.

plugin command("LocalDictionary.dll", "clear global dictionary")
thread {
    plugin command("LocalDictionary.dll", "init local dictionary")
    plugin command("HTTP post.dll", "http container") {
        plugin command("LocalDictionary.dll", "local dictionary add", "captcha path", "{$special folder("Desktop")}\\TBRD2dKYxYlo.jpg")
        plugin command("LocalDictionary.dll", "thread container") {
            set(#capcha d, $plugin function("HTTP post.dll", "$http captcha dialog", $plugin function("LocalDictionary.dll", "$local dictionary get", "captcha path")), "Global")
        }
    }
}

But when I use the set command set to 'local' it works without any issues. but I need to make it work with local dictionary plugin -to be thread safe..any ideas?

thread {
    plugin command("HTTP post.dll", "http container") {
        set(#captcha, "{$special folder("Desktop")}\\TBRD2dKYxYlo.jpg", "Local")
        plugin command("LocalDictionary.dll", "thread container") {
            set(#capcha d, $plugin function("HTTP post.dll", "$http captcha dialog", #captcha), "Global")
        }
    }
}
