I'm trying to buffer polygons I've created but I fail. I keep getting "WARNING 000117: Warning empty output generated" warning. I set distance, I set unit, I set side type to "exclude polygon itself", method: planar and no dissolve. Why am I failing? What's wrong with the buffer tool or my polygons? I've tried repair geometry but it didn't help.
NOTE: I'm using ArcGIS Pro 2.2.3
