"Invalid Schema, Check Your Dataset Query" error
I only saw a few questions related to this on Dojo and figure I might ask. My dataflow has always ran fine (created in May 2021) but yesterday there was an error that showed up. I'm not able to preview the dataset, and I tried to refresh the ETL multiple times and reset the schema (deleted all columns from the python script schema and re-added again) and I'm still getting an error.
This error is really vague and I am not sure how to troubleshoot.
Can someone please help? Thanks!
