converter not running?

[dlovell]

When I run the script below, I get the subsequent terminal output.

The print of c0 shows that the dates field is not a tuple.

Notably, the validator does not seem to be catching that dates is not a tuple.

Is there anything obviously wrong I'm doing here?

import pandas as pd

import attr
from attr import (
    field,
    frozen,
)
from attr.validators import (
    instance_of,
    deep_iterable,
)


@frozen
class Calendar0:
    dates: field(validator=deep_iterable(instance_of(pd.Timestamp), instance_of(tuple)), converter=tuple)


print(f'attr version: {attr.__version__}')
dti = pd.date_range('2023-01-01', freq='D', periods=10)
c0 = Calendar0(dti)
print(c0)

attr version: 22.2.0
Calendar0(dates=DatetimeIndex(['2023-01-01', '2023-01-02', '2023-01-03', '2023-01-04',
               '2023-01-05', '2023-01-06', '2023-01-07', '2023-01-08',
               '2023-01-09', '2023-01-10'],
              dtype='datetime64[ns]', freq='D'))
