   ### Search before asking
   
   - [X] I searched in the [issues](https://github.com/apache/paimon/issues) 
and found nothing similar.
   
   
   ### Paimon version
   
   Paimon 1.0
   paimon-spark-3.3-1.0-20241129.002716-51.jar
   
   ### Compute Engine
   
   Spark 3.3.4
   
   ### Minimal reproduce step
   
   In Spark, if we create table by the following sql:
   
   ```sql
   use paimon;
   
   CREATE TABLE T (
       id INT,
       name STRING
   );
   
   select * from `T$binlog`
   ```
   
   we will get the following error:
   ```shell
   Caused by: java.lang.ClassCastException: org.apache.paimon.types.IntType 
cannot be cast to org.apache.paimon.types.ArrayType

org.apache.paimon.utils.BulkFormatMapping$BulkFormatMappingBuilder.pruneDataType(BulkFormatMapping.java:189)
           at 
org.apache.paimon.utils.BulkFormatMapping$BulkFormatMappingBuilder.lambda$readDataFields$1(BulkFormatMapping.java:160)
           at java.util.Optional.ifPresent(Optional.java:159)
   ```
   
   But if we create table by the following sql:
   ```sql
   use paimon;
   
   CREATE TABLE students (
       name STRING,
       age INT,
       course STRUCT<course_name: STRING, grade: DOUBLE>
   )
   
   select * from `students$binlog`
   ```
   We can obtain the results normally.
   
   I haven't found any similar errors in flink.
