ERROR DotnetRunner: null

Getting an error when submitting a job description after following these [steps](https://docs.microsoft.com/en-us/azure/synapse-analytics/spark/apache-spark-job-definitions#create-an-apache-spark-job-definition-for-net-sparkcf). FYI when using the python example it works with no issues.
[sparkpoolpoc-19-application_1638810855048_0001-Driver (stderr).log](https://github.com/Azure-Samples/Synapse/files/7662696/sparkpoolpoc-19-application_1638810855048_0001-Driver.stderr.log)

Start by reviewing the linked .NET Spark job-definition steps and the attached sparkpoolpoc-19-application_1638810855048_0001-Driver.stderr.log, then reproduce the submission using the same description. Compare the result with the working Python example; the issue is done when the .NET job submits successfully without the reported null error.
