Unable to connect to mysql database on WSO2

I am new to WSO2 and trying to connect with MySQL database on a windows machine. I have followed the documents but still no luck. change the deployment.toml file as below

[database.apim_db]
type = mysql
url = jdbc:mysql://localhost:3306/wso2_gateway_api?autoReconnect=true
username = hide
password = hide
driver=com.mysql.cj.jdbc.Driver

[database.shared_db]
type = mysql
url = jdbc:mysql://localhost:3306/wso2_gateway?autoReconnect=true"
username = hide
password = hide
driver=com.mysql.cj.jdbc.Driver

I have run the scripts as well on the database created above. below is the error
