TypeError: argument of type 'azureml.dataprep.rslex.StreamInfo' is not iterable

Start by running the provided NycTlcYellow reproduction with azureml-opendatasets==1.55.0, then inspect azureml/opendatasets/dataaccess/_blob_accessor.py, especially get_spark_dataframe and _get_relative_path. Trace why target_paths contains a StreamInfo and compare the pandas and Spark paths; done means to_spark_dataframe completes without the reported TypeError.

Hi, I encountered below error, I have azureml-opendatasets==1.55.0
