aktuelles_Jahr = datetime.today().year

df_nicht_erfasst = df.query("Fälligkeitsdatum.dt.year == @aktuelles_Jahr and "
"Fälligkeitsdatum.dt.month == @aktueller_Monat and "
"Buchungsart == 'Überweisung' and "
"`gesendet am` == ''")Issue Description
After updating to pandas 2.2, when I run a program with the last line above, there is now the following warning displayed:
FutureWarning: The behavior of 'isin' with dtype=datetime64[ns] and castable values (e.g. strings) is deprecated. In a future version, these will not be considered matching by isin. Explicitly cast to the appropriate dtype before calling isin instead.
However, the line referenced in the warning does not contain any isin function.
Also, I am unclear what I am now supposed to do to remedy this warning.
Expected Behavior
Clarification about why this is about isinand pointer to explanation + example about how to change the code
