I'm using 2.8.1 QGIS version (Wien) and I have a raster layer with FWI values and a vector with district polygons.

What I wnatwant is to calculate the mean pixerpixel FWI value per district.

I know the Zonal Statistics funtion, but when I use her appears this error:

"Algorithm Zonal Statistics starting...
'NoneType' object has no attribute 'exportToWkt' See log for more details".

I don´t know what could be the problem. I'm using the same CRS layers.

Any help?
