The Zarr v2 specification states the the following about the filters field:
filters
A list of JSON objects providing codec configurations, or null if no filters are to be applied. Each codec configuration object MUST contain a "id" key identifying the codec to be used.
n5-zarr encodes "raw compression" as [] rather than null. Tensorstore only accepts null when there are no filters.
