KeyError when trying to get prediction intervals with MiddleOut

[pkwan9]

This following error pops up when I try to get prediction intervals with MiddleOut. It doesn't show up if I use other reconciliation methods.

File "<....>/hierarchicalforecast/core.py", line 313, in reconcile sorted_quantiles = np.reshape(fcsts_model['quantiles'], (len(Y_tilde_df),-1)) KeyError: 'quantiles'

I have the same error, when using both MiddleOut and TopDown.
