My objective is to use the 'Exists' data flow activity to check if the data I'm processing already exists in a directory in Azure Data Lake Storage. The issue I'm having is I'm wanting to access data within subdirectories. In the past, I've used a double wildcard (**) to get to data in all subdirectories, but it doesn't seem to be working in this case.
All of my images will be provided below. I've provided a screenshot of my current data flow, source activity, and exists activity, and the error I receive.
My top directory is 2021. Subdirectories include months and days, where all data is stored. In my source activity, I placed the double wildcard, but when I previewed the data, I received the error you see below, and it appears as though it is not seeing any of the data in the subdirectories.
If anyone has any thoughts/ideas on this, it would be much appreciated. Thank you.
