   Correct @RussellSpitzer . I verified even after updating `TableProperties.DEFAULT_NAME_MAPPING` to the proper json value containing the field-id, names and fields exactly mentioned in [here](https://iceberg.apache.org/spec/#name-mapping-serialization) such as in one of my table's metadata contains : 
   ```
   "properties" : {
       "schema.name-mapping.default" : "[{\"names\":[\"_fivetran_synced\"],\"field-id\":1},{\"names\":[\"id\"],\"field-id\":2},{\"names\":[\"attr\"],\"field-id\":3}]",
       "table_type" : "ICEBERG"
     },
   ```
   
   Still IcebergGenerics fails to read the table and fails with the same kind of exception : 
   ```
   java.lang.ClassCastException: class org.apache.iceberg.types.Types$StringType cannot be cast to class org.apache.iceberg.types.Types$TimestampType (org.apache.iceberg.types.Types$StringType and org.apache.iceberg.types.Types$TimestampType are in unnamed module of loader 'app')
   ```
   
   Do you think this should be considered as bug and it should be fixed in IcebergGenerics?
