Hi, I'm new to Create ML. I was trying to create a simple sentiment analysis model. My input file is cleaned JSON data from Apple reviews with two fields, "label" (pos/neg) and "text" (the content with sentiment). Training runs successfully. However, when I try to perform a test with similar data with the same fields in either JSON or CSV format, I continue to get the following error. Testing Error: Expected directory at URL at "filename.json" I've tried using different data sets but always receive the same error. Does anyone have any idea what I'm doing wrong?
