When looking at the dataframe under the debugger, it looks like it skipped
the null values ok:
```
df
DataFrame()
+---------------------+-------+
| time_window | count |
+---------------------+-------+
| 2024-09-07T10:01:00 | 2 |
| 2024-09-07T10:03:00 | 2 |
+---------------------+-------+
df.schema()
time_window: timestamp[ns]
count: int64 not null
```
So I am pretty confused about the error message.
```
return self.df.to_arrow_table()
^^^^^^^^^^^^^^^^^^^^^^^^
File "pyarrow/table.pxi", line 4865, in pyarrow.lib.Table.from_batches
File "pyarrow/error.pxi", line 155, in
pyarrow.lib.pyarrow_internal_check_status
File "pyarrow/error.pxi", line 92, in pyarrow.lib.check_status
pyarrow.lib.ArrowInvalid: Schema at index 0 was different:
time_window: timestamp[ns]
count: int64 not null
vs
time_window: timestamp[ns]
count: int64
```
