S3 Data Source Configures Successfully But Suite New Fails with New S3 Datasource

Following the instructions here on configuring an s3 data store gave me a success message but creating a new suite based on the s3 data source returns the following error:

   if len(value["names"]) > 0:

TypeError: list indices must be integers or slices, not str

Any advice or insight greatly appreciated!
