Neo4j ETL import data from mariaDB to neo4j

When I mapped and imported data from mariaDB to neo4j, I received following exception, hope someone can point me to where I should look for solution. Thanks.

  • Data imported with errors. Below the list of errors.
  • For exception RuntimeException we got the following errors:

Process failed Unable to retrieve the value from the column ROW_INDEX, sqlType: null, value class: null

  • Closing driver instance 48305285
  • Closing connection pool towards localhost:7687

what exactly did you do, please share your process and where in the process the error occurred

This issue was somehow no longer occurred, thanks.
