Invalid connection type in catalog

Resolve the error that occurs due to an invalid connection type in catalog.

When a valid connection type cannot be detected, the following error occurs:
2020-06-30 22:37:09,628 - WKCConnector - ERROR - Could not find a supported connection in the supplied catalog

This error might occur in the scenario when the connection type within the Watson Knowledge catalog (WKC) does not match the connection type on Spectrum Discover. For example, if you try to export metadata from an IBM Spectrum® Discover Cloud Object Storage (COS) source to a WKC catalog, which does not have an IBM Cloud® Object Storage connection. The error can also occur if you have an IBM Cloud Object Storage bucket on WKC mapped to an on-Premises IBM Cloud Object Storage bucket that is configured on IBM Spectrum Discover.
