[CX] disconnect feed beer_feed from table beers giving Error through Web Interface

Tried few queries by connecting to beer-sample and then travel-sample.

They all gave correct results.

Tried disconnecting from beer-sample:

use couchbase;

disconnect feed beer_feed from table beers;

Above gives ERROR. There is no more description displayed along with ERROR.

I am still able to get results from queries on beer-sample.

If you try : connect feed beer_feed to table beers;

You get the correct error message:

Error: Feed beer_feed is already connected to dataset beers

Attaching logs also.
