In QGIS 3.4, when I try to get a zonal histogram it returns an error related to invalid geometries in the vetor layer. I've fixed geometries and, despite the layer have seemingly only valid geometries (as showed in the check geometry results), the "zonal histogram" algorithm keeps in the "calculating field" stage, without progress.

To solve this, try this, just go to the process toolbox, then vector geometry and run Fix geometries on the input layer enter image description here

This will generate a new layer, corrected, with which you will work

  • Hi Luis, the problem still persists, even after fix geometries. The algorithm remains processing, "endlessly". Commented Oct 23, 2020 at 12:28
