{type} no abstract type ValueSet

Error message

{type} no abstract type ValueSet 

What it means

Velox protocol serialization error: serializing a ValueSet whose _type is none of equatable/sortable/allOrNone. to_json exhausts the known subclass branches and throws TypeError, meaning an unknown ValueSet variant reached the native protocol conversion.

Solutions

1. Ensure only EquatableValueSet, SortedRangeSet, or AllOrNoneValueSet are serialized
2. Add the missing ValueSet subclass to the native protocol
3. Check TupleDomain construction producing the unexpected variant
