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.
