Error creating bean with name 'worklight-direct' - ibm-mobilefirst

Question

I am using the MobileFirst Platform on Liberty profile and DB2 for database.
I deployed the new project war file on the Mobile First Platform. after the deployment I restart the server when I try to access the Mobile First Platform console I am getting the below error.
but the project schema, Mobile First Platform schema and report schema are there and currently there has not been any change on DB2 side.
Caused by: org.springframework.beans.factory.BeanCreationException: Error
creating bean with name 'worklight-direct' defined in URL
[wsjar:file:/appl/was1/IBM/WebSphere/Liberty/usr/shared/resources/hamfactoryapps/lib/worklight-jee-library.jar!/conf/spring-server-core.xml]:
Invocation of init method failed; nested exception is
java.lang.RuntimeException: FWLSE0206E: The project /hamfactoryapps failed
to initialize, because the project database schema for data source
jdbc:db2://xxxxxx:51000/WRKLGHT is from version N/A,
which is not supported by the server from version 6.3.0.00.20141127-1357.
Use the MobileFirst ant tasks to upgrade the project database schema.

I delete the old schema and I create the new one, after I'm getting the below error.

This error would happen if you are trying to access the wrong schema than the one you have intended to use. Double-check this.
Also make sure that you have used the correct create-worklight-db2.sql. See the documentation here: http://www-01.ibm.com/support/knowledgecenter/SSHS8R_6.3.0/com.ibm.worklight.installconfig.doc/devref/t_ant_tasks_configure_dbs_wlconsole.html
purge the database and re-create it based on the above.
