Error with findTrainingData.initAndExecute() in Entity Resolution POC: NoSuchMethodError in Apache Spark Encoders.row...

Hi, am trying to implement a POC for entity resolution and followed the steps in the febrl example guide, the findTrainingData.init() does not yield any error but findTrainingData.initAndExecute() is always yielding an error like below: ['--phase', 'findTrainingData'] arguments for client options are ['--phase', 'findTrainingData', '--license', 'zinggLic.txt', '--email', 'zingg@zingg.ai', '--conf', 'dummyConf.json'] java.lang.NoSuchMethodError: org.apache.spark.sql.Encoders.row(Lorg/apache/spark/sql/types/StructType;)Lorg/apache/spark/sql/Encoder; File /local_disk0/.ephemeral_nfs/envs/pythonEnv-f9fbb223-fc34-469c-80c0-836eed61ae9a/lib/python3.10/site-packages/zingg/client.py:144, in Zingg.initAndExecute(self) 142 self.client.execute() 143 else: --> 144 self.client.execute() Also, there are no marked/unmarked pairs getting stored after the findTrainingData task
