Error: "EMPTYTAIL"

[Anonymous]

I'm trying to import data via a simple R script that appends some API call results to a local CSV. It executes perfectly in RStudio. However, I get an interesting error when I try it in Power BI:

This persists even after retrying the connection. Is anyone aware of what causes this and/or how to address it?

After a few hours of debugging I found out that my Data Frames had empty rows AND empty columns. 

I got rid of BOTH and it worked. 

No more "EMPTYTAIL" msg.
