De-serialization issue while connecting to a database

Hi,

 

I have created a sample table in mysql and tried to create a form data model based on a schema-> table.

While trying to do testing for read and insert I get the following error.

 

While reading : Deserialization not allowed for class [Ljava.lang.String; (on Thu Jun 04 16:49:46 IST 2020)

 

While inserting :  {
"errorMessage": "java.lang.UnsupportedOperationException: Deserialization not allowed for class [Ljava.lang.String; (on Thu Jun 04 16:50:05 IST 2020)"
}

 

Please help.

 

Thanks,

Bibhu.

            • Whitelist sun.util.calendar package.
              • Open feilix web console in your browser window
              • Search and open Deserialization Firewall Configuration In the whitelist field add sun.util.calendar package and save

              I have already added the below URLs.

              com.mysql.jdbc.Driver

              jdbc:mysql://localhost:3306/mysql

               

              Can you please let me know what else need to be added?

                @bibhunayak 

                Please locate “DeserializationFirewallImpl” configuration under configMgr( http://<hostname>:<portno>/system/console/configMgr)  and add [ like below.

                I hope this will help.
