Writing HDF5 ValueError

Created by: sancholp

I am trying to save a TimeSeries as HDF5 but am getting a ValueError (see stack trace). The file gets written to the correct directory, but when trying to read it, I get the similar error ValueError: Please specify the HDF5 path via the ``path=`` keyword argument. I am simply writing the file with timeseries.write('file.hdf5', overwrite=True). Any help would be much appreciated.

Traceback (most recent call last):
