A value was not specified for a required property: interface

I am unable to create data sources for Oracle Services. I am getting following error. I am not sure what Interface name I have to use. 

Error: "[d2c][JDBC Cloud driver][Oracle Service Cloud]A value was not specified for a required property: interfacename"

The URL for my services is : https://ebcu-test.fs.us2.oraclecloud.com

If I use "ebcu-test" or just "ebcu" as interface name I get following error.

Error: "[d2c][JDBC Cloud driver][Oracle Service Cloud]Unexpected ContentType: 404 (Not Found): ContentType: text/html Response:"

I was following youtube video "https://www.youtube.com/watch?v=_70BIPDawYM"

She used the prefix of the URL as interface. I am also trying to do the same.

Please help

Thanks
