Neo4j Connector with Spark

Neo4j Graph Platform
1

I want to load the data into neo4j using spark. I have installed apache spark and adding neo4j connector using python code.

df.write.format("org.neo4j.spark.DataSource")
.option("url","url" )
.option("authentication.type", "basic").option("authentication.basic.username", "xx")
.option("authentication.basic.password","xxxx")
.option("query", "MERGE (city:City{locationId:event.LOCALITY_ID}) ON CREATE SET city.city = event.LOCALITY_NAME")
.mode("Overwrite")
.save()

I am using neo4j apache connector.
neo4j-connector-apache-spark_2.12-4.0.1_for_spark_3.jar

However when i am executing , i am getting below error.

21/08/06 11:29:48 ERROR SchemaService: Query not compiled because of the following exception:
org.neo4j.driver.exceptions.ClientException: Variable event not defined (line 2, column 29 (offset: 71))
"MERGE (city:City{locationId:event.LOCALITY_ID}) ON CREATE SET city.city = event.LOCALITY_NAME"

Can some one assist here.

Hello,

I am facing the same issue while executing following Query:

MERGE (account:AccountSS {entityKey: event.entityKey, communityId: event.communityId, appId: event.appId, nativeType: event.nativeType})   MERGE (ap:DBAccessProfileSS {dataCollection: event.dataCollection, name: event.name, description: event.description, displayName: event.displayName})  MERGE (ap)<-[:IS_RELATED_TO_SS]-(account)
in the middle of logs

Though query is executed successfully at the end. But there are exceptions in the log.

Neo4j told this issue is related to the driver. we have used the latest connector jar file and this error is gone.
