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!

More context below:

s3 config

module_name: great_expectations.datasource
    bucket: bucket_name_redacted
    class_name: InferredAssetS3DataConnector
    prefix: bucket/prefix/redacted
    module_name: great_expectations.datasource.data_connector
      group_names: '*'
      reader_method: csv
        sep: ','
      pattern: (.*)
  module_name: great_expectations.execution_engine
  class_name: PandasExecutionEngine
class_name: Datasource
