bug: Comet crashes on DataFrame API

[comphead]

Describe the bug

Faced this bug in https://github.com/apache/datafusion-comet/issues/2793#issuecomment-3561016437

Spark works fine

+------+------+
|c1    |result|
+------+------+
|123456|NULL  |
|12    |12    |
+------+------+

Steps to reproduce

Run the test

test("make decimal") {

    sql("create table t1 using parquet as select 123456 as c1 from range(1)")

    withSQLConf(
      CometConf.COMET_EXEC_ENABLED.key -> "true",
      SQLConf.USE_V1_SOURCE_LIST.key -> "parquet",
      CometConf.COMET_ENABLED.key -> "true",
      CometConf.COMET_EXPLAIN_FALLBACK_ENABLED.key -> "true",
      "spark.sql.ansi.enabled" -> "true",
      "spark.sql.adaptive.enabled" -> "false",
      "spark.comet.expression.Sum.allowIncompatible" -> "true",
      CometConf.COMET_NATIVE_SCAN_IMPL.key -> "native_iceberg_compat",
      "spark.sql.optimizer.excludedRules" -> "org.apache.spark.sql.catalyst.optimizer.ConstantFolding") {

      val df = sql("select * from t1")
      val makeDecimalExpr = MakeDecimal(df.col("c1").expr, 3, 0)
      val makeDecimalColumn = new Column(makeDecimalExpr)
      val df1 = df.withColumn("result", makeDecimalColumn)
      df1.explain("formatted")

      checkSparkAnswerAndOperator(df1)
    }

  }

The Comet crashes with
