     #ERROR : ...

—or—

    #ERROR : Traceback (most recent call last):

    #    raise AttributeError, "%s.%s" % (self._username_, attr)
    #AttributeError: line 150

## Possible Cause

You may see an error like one of these accompanying a Traceback for a script block that tries to use a native Python dictionary for return value from a custom command.

## Suggested Solution

You cannot use the native Python dictionary type as the return value for a custom command, but you can use an ActiveX Scripting Dictionary instead (see Using Python Dictionaries as Return Values).
