   Happy to, just want to understand what the expected write behaviour is for folder-storage & s3. Having the following fail on my end.
   ```
   CREATE TABLE my_catalog.sampledb.my_table (
       id bigint,
       data string,
       category string)
   USING iceberg
   OPTIONS (
       'write.object-storage.enabled'=true, 
       'write.folder-storage.path'='s3://kda-jython-test/some-random-folder/')
   PARTITIONED BY (category);
   
   INSERT INTO my_catalog.sampledb.my_table VALUES (1, "some data", "some category");
   java.lang.NullPointerException
