### Describe the bug
```
Caused by: org.apache.comet.CometNativeException: Cannot evaluate binary
expression because of type mismatch: left List(Field { name: "item", data_type:
Utf8, nullable: false, dict_id: 0, dict_is_ordered: false, metadata: {} }),
right List(Field { name: "item", data_type: Utf8, nullable: true, dict_id: 0,
dict_is_ordered: false, metadata: {} }) .
