Unable to import data services using Data Services Builder - Web UI
Hello,
I am getting an error when i try to import data services and also testing connection / connection for Administration and JDBC under User > Preferences link also is not working. When i click on Test connection, i don't get any response either error or successful message. Also when i invoke http://localhost:8080/vdb-bench URL, getting an error "The host “http://localhost:8080/vdb-builder/v1' is not reachable: Status code: 500" as shown below.
I noticed that server.log has below error message.

Are there any other settings or configuration that we need to do in order to use Data Services Builder ? I am using teiid-8.12.4 and Java 1.8 for Data Services Builder.
Thanks, Mani
