Cannot bake with cage

[wickerman123]

Hey,

So I duplicated my low poly and added a displace modifier to make the mesh encompass the high poly however when I set this mesh as the cage I get the following error:

Traceback (most recent call last):
  File "C:\Program Files (x86)\Steam\steamapps\common\Blender\2.90\scripts\addons\EasyBake.py", line 425, in execute
    vcount_low = len(bpy.data.objects[lowpolyobject].data.vertices)
TypeError: bpy_prop_collection[key]: invalid key, must be a string or an int, not Object

location: <unknown location>:-1

I thought maybe I need to apply the modifier but the same issue occurs. This only happens when I add a cage.
