This error will occur more likely, when you have installed BizTalk360 on a stand-alone server. To resolve this issue, install the BizTalk enterprise adapter pack (in this case WCF-SQL) in the server where BizTalk360 is installed.

You will face similar issue for other enterprise adapters like WCF-Oracle. So, if you are using any of the enterprise adapters, please install them on the server where you have installed BizTalk360.
