When exporting a layer with gradient border as a SVG. SketchTool seems to crash and Sketch doesn't export the asset.
Command we use for SketchTool: ./sketchtool export layers Failedexport.sketch --items=FEB30B8F-4565-4B62-A1B5-5641EFFA0B27 --formats=svg --output=OUTPUTFOLDER
This will give a
Command threw exception
(ECCommandLineDomain:5)
Exporting it as a SVG inside Sketch will just not export it. No error is shown. The console report a <Private> error in this case:

Even ./sketchtool export slices Failedexport.sketch --output=OUTPUTPATH
Will fail if you add slices on those assets.
