I'm trying to use the instructions from "End-to-end data validation strategies in Microsoft Fabric" video with my own data. I'm a newbie here and to the notebooks concept. From the video, I'm on the first phase of Schema Validation (and am thankful for the guidance in the video) I have a parameter node where I've defined the parameter like: fileToTest = "Files/_folder_/_fileName_.csv" Second node is %pip install --q great_expectations --- update--- It seems that the pip Install command is causing at least part of my problems. If I comment it out. I can utilize the fileToTest parameter in subsequent cells, but I can't use the dependent functions. Third node is: import great_expectations as gx gxContext = gx.get_context() validator = gxContext.sources.pandas_default.read_csv(fileToTest) I consistently receive a "NameError" for the reference to "fileToTest". I wanted to validate that the fileToTest parameter works so in the same Parameter node I added (started with dragging the file to the notebook) df = spark.read.format("csv").option("header","true").load(fileToTest) display(df) This works, displaying the content of the CSV. What am I missing?
