java.lang.IllegalArgumentException when using parquet file

Start with ValidatorBase.scala at line 139, then trace initialization through RowBased.scala and NullCheck.scala. Reproduce the config check with the supplied parquetFile and config.yaml, and use the stack trace to confirm the failure no longer occurs while loading the nullCheck configuration.

When trying to run a config check on a parquet file, the following error can be seen:

Ran a spark-submit job as follows:

spark-submit --num-executors 10 --executor-cores 2 data-validator-assembly-20220111T034941.jar --config config.yaml

The config.yaml file has the following content:

numKeyCols: 2
numErrorsToReport: 742

tables:
  - parquetFile: /home/jyoti/Spark/userdata1.parquet
    checks:
      - type: nullCheck
        column: salary

I got the userdata1.parquet from the following github link:
https://github.com/Teradata/kylo/blob/master/samples/sample-data/parquet/userdata1.parquet
