Hi Alireza, I wrote some test code using your layer creation and neighbour search code that you pasted, and it works fine. So what I think has happened is that you have somehow added nodes with a different layer config to the same index that you are now using for WKB. Perhaps the nodes used to be points in a simple point layer, and now you changed to a WKB layer, it is no longer compatible.
I can make a few suggestions: - Make sure your nodes were added using the layer.add(Geometry) method. If you used layer.add(Node) then it is your responsibility to make sure the node conforms to the same layer config that you are planning to use. For example, do not add a simple point node (with lat/lon attributes) to a WKT layer, or you are likely to create this kind of issue. - Since you are working with points, can I suggest you not use the WKB layer config, but rather use the SimplePointLayer, as created by SpatialGraphDatabase.createSimplePointLayer(name) or SpatialGraphDatabase.createSimplePointLayer(name,xProp,yProp) Regards, Craig
