Bug report #20221
Gererate Contours from Points
|Affected QGIS version:||3.2.3||Regression?:||No|
|Operating System:||Windows 10 64 bit||Easy fix?:||No|
|Pull Request or Patch supplied:||No||Resolution:|

I have a shape file containing random points with values to contour after taking the difference of two fields. Some points have Null values. I used the following expression in the Generate Contours tool to select only non Null values:
CASE WHEN "topsTOP" is not null and "topsELEVATION" is not null and "topsFORMATION" Like '%Prec%' THEN "topsELEVATION" - "topsTOP" END
This would not function within the tool but I could use the same expression to select the points without Nulls and tick the Selected Features Only box and this would work. Shouldn't Case work within the Generate Contours Tool?

QGIS expression works fine. So, there must be an issue with the plugin:
