Automator Stop Capture error

Question

I was trying to make a screen capture service, but have been hitting errors in the Start Capture and Save Capture actions. I tried to make a service as simple as New Screen Capture > Wait for User Action > Stop Capture, but it gives me an error on the Stop Capture action (even though it does stop the recording). The error just says "can't make missing value into type alias."

Cool, at least that lets the workflow keep going. It's still not returning the video
Here's a script that returns the new Quicktime video to the next action, even if the user has already opened other video.
on run {input, parameters}
    tell application "QuickTime Player" to if exists document 1 then
        try
            set screenRecordingDoc to first document whose its current screen compression's name is not ""
            set allDocs to name of documents
            try
                stop screenRecordingDoc -- to stop capture
            end try
            repeat 5 times
                my waitSec(1)
                if not (exists screenRecordingDoc) then exit repeat
            end repeat
            repeat with tDoc in (get documents)
                if name of tDoc is not in allDocs and file of tDoc is missing value then -- a new doc name ("Untitled x") in the list of names, and this document is not a file
                    return contents of tDoc -- return the new Quicktime video
                end if
            end repeat
        end try
    end if
    return {} -- no screen capture or no document
end run
on waitSec(n)
    do shell script "sleep " & n
end waitSec
