TypeError: 'TestTree' object is not callable

Running the sample notebook "Testing Models -- Sentence Pair Classification".
Following code:

# Launch AdaTest!

tests.adapt(
    model,
    generator=gen_model,
    auto_save=True, # Set to "True" to automatically save tests as they are made.
)

# Optionally:
#adatest.serve(tests(model, generator=gen_model, auto_save=True), host='127.0.0.1', port=8080)

Doesn't generate interactive Widget through VSCode or AzureML Notebook experience. Probably not unsurprising. However, when uncommenting the .serve function to generate standalone client, get the error:

---------------------------------------------------------------------------

TypeError: 'TestTree' object is not callable

Running in Jupyter, the widget loads, but then just spins when clicking 'Suggest tests'.
