Attribute error in gravity inversion


I recently updated my geoapps. When I tried to run a gravity inversion, I got the following error and I don’t know what to do. Help please. Thanks.

AttributeError Traceback (most recent call last)
File ~\Downloads\geoapps-main\geoapps-main\geoapps\inversion\potential_fields\, in InversionApp.write_trigger(self, _)
1201 new_obj = obj.copy(parent=new_workspace, copy_children=False)
1202 for d in data:
→ 1203 if new_workspace.get_entity(d.uid)[0] is None:
1204 d.copy(parent=new_obj)
1206 if self.inversion_type.value == “magnetic vector”:

AttributeError: ‘NoneType’ object has no attribute ‘uid’

Hi Jenny,

Hard to tell like that.
Would you mind trying with the develop branch:

Otherwise, send me your geoh5 with a screenshot of the inversion menu - I can try it on my side to find out:



Hi Dom,
Sorry for the very late reply, been away sick.
A colleague, Craig Miller, is helping me sort it out. I believe you have a paper together in 2017(?). Will let you know how it goes.
