KeyError: 'min' when generating report structure

Getting KeyError: ‘min’ in the generate report structure step.

I am unable to share the dataframe as it is confidential. The dataframe structure however is:

Int64Index: 425876 entries, 0 to 425875

KeyError: 'min ```

Code used:
```pandas_profiling.ProfileReport(PO)```

Version information: 
Python version: 3.9.2
Environment: Jupyter Lab
Pandas profiling: 2.11.0

Additional context: I don't have much experience but I think the problem may be that the code cannot calculate the min for datetime objects. Previous versions were able to do this but they are no longer able to summarise the results with this dataset.

Thanks for the help in advance!

Thanks for reporting. I suspect the error is caused by POLineCancDate having 0 non-null values.

I am getting KeyError: 'data' for a frame without any zero-non-null counts.
