getting nodes with location specified via NeomodelPoint

Question

getting nodes with location, specified with NeomodelPoint give an error "Invalid instantiation via no arguments", while setting node in the same way works well (below it gives ConstraintError). What is the right way of getting nodes with specific location?

location=(51.3454, -6.2434)
try:
    property = Property.nodes.get(location=NeomodelPoint(location,crs='cartesian'))
except:
    property = neo4j.Property(location=NeomodelPoint(location,crs='cartesian')).save()

ValueError: Invalid instantiation via no arguments. A Point needs default values either in x,y,z or longitude, latitude, height coordinates

ValueError: Invalid instantiation via no arguments. A Point needs default values either in x,y,z or longitude, latitude, height coordinates

During handling of the above exception, another exception occurred:

Answer 1

That was a module bug, which is eventually fixed
