CallbackOutputValidationError: 


A Dash Callback produced an invalid value!

Dash tried to update the `figure` prop of the
`Graph` with id `output2` by calling the
`crash_it2` function with `(1)` as arguments.

This function call returned `{'layout': {}, 'data': {'y': [1, 2, 3], 'x': [1, 2, 3], 'type': 'scatter'}}`, which did not pass
validation tests for the `Graph` component.

The expected schema for the `figure` prop of the
`Graph` component is:

***************************************************************
{'validator': 'plotly_figure'}
***************************************************************

The errors in validation are as follows:

* figure	<- Invalid Plotly Figure:


    Invalid value of type '__builtin__.dict' received for the 'data' property of 
        Received value: {'y': [1, 2, 3], 'x': [1, 2, 3], 'type': 'scatter'}

    The 'data' property is a tuple of trace instances
    that may be specified as:
      - A list or tuple of trace instances
        (e.g. [Scatter(...), Bar(...)])
      - A list or tuple of dicts of string/value properties where:
        - The 'type' property specifies the trace type
            One of: ['mesh3d', 'splom', 'scattercarpet',
