I just forgot to choose a field in Processing's Convex Hull tool while I was trying to generate separate hulls per field value and was greeted with an non-explanatory error message:

Algorithm Convex hull starting...

float division by zero See log for more details

Please make sure the user did select a field and alert them if not.

This is fixed in 3.0 - the decision to use the per field mode is made by whether the user selects a field or not

• resolution was changed from to fixed/implemented
