CBTransfer is broken for importing to CSV file from couchstore-files

Using 3.0.0-608

For cluster with 2 nodes and around 10K data with bucket default ran the following command. We were using TAP

Command Used
/opt/couchbase/bin/cbtransfer couchstore-files:///opt/couchbase/var/lib/couchbase/data csv:/data/disk.csv -b default -u Administrator -p password

Seeing the issue as follows:

Traceback (most recent call last):
