Error when using "update" mode

[CharlieMott]

I receive the following error when using "update" mode:

    Updating alert 'Applications_BTDF': FAILED (Error: 6)
    
    Exception: Value cannot be null.
    Parameter name: g

Looking into this:

• The json field to send the Alarm ID is "alarmId" not "id" (this is what the json schema specifies (if not the sample). I've tested this works using the "try it out" page).
