MySQL - java.sql.SQLException: Unknown character set index for field..

[Anonymous]

Good Day,
I am getting the following error when I run my job that reads data from MySQL db table using a tMySQLInput component.
java.sql.SQLException: Unknown character set index for field ....... received from server.
I have data that has special characters so my characterset is definied as "utf8mb4_general_ci" when creating the tables (varchar fields).
Please see attached Talend job along with the MySQL connector modules installed. Is there a specific connector that works to resolve this issue? How can we resolve this issue. Please advise.
Error details below:
Exception in component tMysqlInput_6

Hi
A user met the same issue, he fixed it by upgrading the mysql connector to another high version. Please see this page. 
Hope it would help.
