Using Node-Red with Cloudant - type error when set up Cloudant out node

Hi there,

I'm working with Node-Red and Cloudant, trying to query data from a Cloudant database file. Using the node-red-node-cf-cloudant nodes.
This works fine with the database being automatically detected by Node-Red, but when I try to use the host, username and password from the service credentials, I get the error

TypeError: Cannot read property 'match' of null

I'm sure I can log in my Cloudant instance, which belongs to WIoT platform. My end goal is to query docs from Cloudant using Node-Red running on IBM Cloud.

Thank you,
DJ
