Reproducible example

import polars as pl
import datetime as dt

s = pl.Series([d1])
s.search_sorted(d1)

The error message from your example is for the Series constructor, not search_sorted().

[davidia]

The Series in my example constructs just fine. Somewhere in search_sorted another Series is constructed and that's the one that fails.

[cmdlineluser]

It seems it ends up calling pl.Series(d1) in this case (line 3605) which is causing the error.

https://github.com/pola-rs/polars/blob/61a6c196b568a96c84377cd2b2048d887bd0db2a/py-polars/polars/series/series.py#L3603-L3605

Whereas it would want to instead perform the operation inside the isinstance check?

>>> pl.select(pl.lit(s).search_sorted(d1)).item()
0
