Build-Runner generation is failing for classes that extends HiveObject. Without this extension, the build runs successfully. Is this a known issue with a solution?
One of the affected classes:
@HiveType(typeId: 3)
@JsonSerializable()
class CustomerModel extends HiveObject{
@HiveField(0)
String? id;
@HiveField(1)
String? title;
...

I can provide more information if needed to find a solution for this problem.
Thank you for answering in advance.
This was fixed in v6.4.1 – just need to get the latets https://pub.dev/packages/json_serializable/changelog#641
