This bug or one with the same error message also seems to prevent R Arrow
from reading Parquet files with Categorical or Enum columns created in Python
Polars.
Reprex tested with Python Polars 1.31.0 and R Arrow 20.0.0.2:
```python
import polars as pl
data = pl.DataFrame({"x": ["a", "b"]}, schema={"x": pl.Categorical()})
data.write_parquet("test.parquet")
```
```r
library("arrow")
read_parquet("test.parquet")
```
