What happens?

with duckdb 1.1.0 I get the following error when selecting over a json file. multiple different json files. also some json files work.

pyo3_runtime.PanicException: Arrow datatype Extension("arrow.json", Utf8, Some("")) not supported by Polars. You probably need to activate that data-type feature.

with duckdb 1.0.0 everything works fine

To Reproduce

duckdb.sql("SELECT unnest(entry, recursive := true) FROM read_json_auto('test.json', filename=true)").pl()
