I was experiencing the same issue on our org. I reset the ELT script back to a default version without builder input, ran the Data flow Manually, it was successful. I then added some extra objects and various fields to the ELT Data flow via the dataset builder and the flow was successful again.
Below is my "default" version of a ELT JSON, This should work with all orgs:
