Google AppEngine TaskQueue throws Caused by: java.lang.IllegalArgumentException: Invalid URL : null

When I try to add to the queue, it gives this exception. It works in development but not production.

Code

    queue.add(withUrl("/worker").param("userId", Utils.getUserId()).param("storeType", storeType)
            .param("associate", String.valueOf(associate)).param("fsm", String.valueOf(fsm)).param("sa", String.valueOf(sa))

            .param("folder", folder).param("folderId", folderId)
            .param("from", getUserEmail()).param("subject", subject).param("body", body)
            .method(Method.GET));

web.xml

<servlet>
    <servlet-name>Worker</servlet-name>
    <servlet-class>com.onixnet.sdm.server.WorkerServlet</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>Worker</servlet-name>
    <url-pattern>/worker</url-pattern>
</servlet-mapping>

queue.xml

<queue-entries>
    <queue>
        <name>default</name>
        <rate>1/s</rate>
    </queue> 
</queue-entries>

I had to use Method.POST instead of GET, and in the worker task servlet, use doPost(). I believe the request was too large for a GET. The problem was Google did not provide a useful error message, and instead used a cryptic one.
