F5 LTM and Javascript error

I am facing a similar issue with kronos. I have two VIPs listening on HTTP & HTTPS. The HTTP has a simple https redirect to the main page, and the HTTPS VIP with a streaming profile has the following iRule:

when HTTP_REQUEST {
     tell server not to compress response
    HTTP::header remove Accept-Encoding

     disable STREAM for request flow
    STREAM::disable
}
when HTTP_RESPONSE {
     catch and replace redirect headers
    if { [HTTP::header exists Location] } {
        HTTP::header replace Location [string map {"http://" "https://"} [HTTP::header Location]]
    }

     only look at text data
    if { [HTTP::header Content-Type] contains "text" } {

         create a STREAM expression to replace any http:// with https://
        STREAM::expression {@http://@https://@}

         enable STREAM
        STREAM::enable
    }
}

There's a run report instance that throws an undefined javascript error when accessing the web-app on the F5.
