Hello, 
How can handle this error when we use autoloader with spark.readStream 
(com.databricks.sql.cloudfiles.errors.CloudFilesException) [CF_EMPTY_DIR_FOR_SCHEMA_INFERENCE] Cannot infer schema when the input path `/Volumes/default/landing/source/bundle/bundle_test/` is empty. Please try to start the stream when there are files in the input path, or specify the schema. SQLSTATE: 42000
