The logical type causing problem is indeed `beam:logical_type:date:v1`.
#24888 in the error message is more clear:
```
java.lang.RuntimeException: java.lang.IllegalArgumentException: Unable to
encode element 'GenericData{classInfo=[f], {dt=2022-12-21}}' with coder
'SchemaCoder<Schema: Fields:
Field{name=dt, description=, type=LOGICAL_TYPE<beam:logical_type:date:v1>,
options={{}}}
Encoding positions:
{dt=0}
```
What confuses me is here:
https://github.com/apache/beam/blob/37c7bee5602e7942fcae8d9b2bafbc8fa86ed7b7/sdks/java/core/src/main/java/org/apache/beam/sdk/schemas/SchemaCoderHelpers.java#L85-L89
value is a java.time.LocalDate, then Date.toBaseType(value) should return a
Long to baseType. However `baseType` feed to baseTypeCoder(VarLongCoder).encode
gets a java.time.LocalDate. Not sure how this happened. The
`SchemaCoderHelpers` class does not change in recent months.
