KeyError: 'components' and AttributeError: components when running Jupyter Notebook 03_Run_Inversion.

Hi. I was testing with the Jupyter Notebooks in the tdmtpy/examples/notebooks/ directory to check if the code works well. However, I got KeyError: 'components' and AttributeError: components errors when I executed the third cell of the notebook 03_Run_Inversion which looks like follows:

# Pass the parameters to the Inversion object and launch the inversion
# The default is to plot all solutions
tdmt = tdmtpy.Inversion(config=config)
tdmt.invert()

The printed errors look like follows:

Deviatoric Moment Tensor Inversion
Depth = 10.0000 km
Mw = 4.32
Percent DC/CLVD/ISO = 93/7/0
VR = 51.69%%

Deviatoric Moment Tensor Inversion
Depth = 12.0000 km
Mw = 4.27
Percent DC/CLVD/ISO = 88/12/0
VR = 53.74%%

Deviatoric Moment Tensor Inversion
Depth = 20.0000 km
Mw = 4.32
Percent DC/CLVD/ISO = 93/7/0
VR = 51.64%%

AttributeError: components

I would like to know what might be the cause of these errors.
