Error TypeError: First argument must be a string, Buffer, ArrayBuffer, Array, or array-like object.

Hi,

I am having trouble with adding a thing. Here's what I get in command line:

debug:

  args:

     { id: '11223344', description: 'Piano Forte' },
     'test' ] }

This happens in this line:

// Invoke the request from the user object.
        var tx = user.invoke(invokeRequest);

The debug in the first code shows invokeRequest, after that it fails.

Please nevermind the issue. This was due to incorrect passing of a parameter.
