   we can reproduce this error using the following sql (spark3.2, iceberg0.13 or 0.14), prod is the name of catalog:
   ```
   CREATE TABLE prod.db.sample (id bigint, data string, category string) USING iceberg PARTITIONED BY (category) TBLPROPERTIES('format-version' = '2');
   
   ALTER TABLE prod.db.sample DROP PARTITION FIELD category;
   
   ALTER TABLE  prod.db.sample DROP COLUMN category;
   ```
   Even though I deleted this column using JAVA API,  I met NullPointerException when using this table.
