GitHub user trxcllnt closed the discussion with a comment: [JS] Decoding `Dictionary<Uint32, Utf8>` incorrectly.
> Does arrow-js have a Slack or Discord? I wasn't able to find anything. There is an arrow-js channel in `the-asf.slack.com`. The rust flight doc says > The current implementation does not support “delta” dictionaries so a new > dictionary batch will be sent each time the encoder sees a dictionary which > is not pointer-equal to the previously observed dictionary for a given > `dict_id`. The JS implementation supports either replacing or appending (i.e. "delta") dictionaries. Perhaps the Rust implementation is replacing dictionaries it's already sent with ones that have fewer elements, and that's why you're seeing a null value?
