NEO4J-ETL Import error with null pointer exception

Neo4j Graph Platform ETL-Tool
1

Hi everyone, I'm trying to import data from a MySQL local database version 8.0.21 to Neo4j using the neo4j etl tool version 1.5.1 on the neo4j desktop version 4.2.5.

I get this error when I try to import data using direct import or batch mode.

import error
import error1891×977 62.8 KB

When I run the command in the logs section on the terminal I get the error : - Illegal command (ParseOptionMissingException: Required option 'RDBMS user' is missing)

Here are my logs:

Empty password to MySql can cause this. Set password to your MySql and try again.

If you run into any issues use the below settings:
useSSL=false
allowPublicKeyRetrieval=true
