not yet implemented: Writing Null to JSON #1504

Closed zubakskees closed 1 year ago

zubakskees commented 1 year ago

Got this while using Polars write_json on a DataFrame with some null values:

thread '<unnamed>' panicked at 'not yet implemented: Writing Null to JSON', /Users/runner/.cargo/registry/src/index.crates.io-6f17d22bba15001f/arrow2-0.17.2/src/io/json/write/serialize.rs:379:18

Strikes me as strange null wouldn't be supported.

Looks like it does write null under some circumstances, but maybe not in the way Polars passes it? I'm going to open an issue there, too.

Unable to reproduce in a small example, so something's weird with my data.
