URL: https://github.com/apache/iceberg/issues/14655
### Apache Iceberg version
1.10.0 (latest release)
### Query engine
Spark
### Please describe the bug 🐞
I ran into "java.lang.NullPointerException: Cannot invoke
"org.apache.iceberg.types.Type.asVariantType()" because "iType" is null" with
the simple table
spark.sql("Create or replace Table customer ( customerId long,
customerDetail variant) using iceberg tblproperties('format-version' = '3')")
spark.sql("""
insert into customer (customerId, customerDetail)
values (1, parse_json('{"name":"customer 1"}'))
""")
spark.sql("describe table customer").show()
+--------------+---------+-------+
| col_name|data_type|comment|
+--------------+---------+-------+
| customerId| bigint| NULL|
|customerDetail| variant| NULL|
+--------------+---------+-------+
spark.version
'4.0.1'
spark.sql("""select schema_of_variant(parse_json('{"name":"customer
1"}'))""").show()
+----------------------------------------------------+
|schema_of_variant(parse_json({"name":"customer 1"}))|
+----------------------------------------------------+
| OBJECT<name: STRING>|
+----------------------------------------------------+
When I ran spark.sql("select customerId from customer").show()
SparkException: Job aborted due to stage failure: Task 0 in stage 32.0

It appears that there is some problem in
org.apache.iceberg.parquet.ParquetSchemaUtil.pruneColumns
iceberg runtime is iceberg-spark-runtime-4.0_2.13-1.10.0.jar
