# VpsGraphOperationError Source: https://www.nianticspatial.com/docs/api/unity/NianticSpatial.NSDK.AR.API.VpsGraphOperationError/ VpsGraphOperationError Error codes returned by VPS graph-based functions. --- ## Declaration public enum VpsGraphOperationError --- ## Fields | Name | Type | Summary | | --- | --- | --- | | static NoGeoreferenceData | VpsGraphOperationError | Code returned when the VPS location that the device is localized to contains no nodes with georeference data. Currently, only publicly available VPS locations have georeference data. | | static None | VpsGraphOperationError | Code returned when no error has occurred. | | static NotInitialized | VpsGraphOperationError | Code returned when VPS is not initialized. Make sure the subsystem has been started. | | static NotLocalized | VpsGraphOperationError | Code returned when the device is not localized to any VPS location. | | static NoTransformToTrackingNode | VpsGraphOperationError | Code returned when the device is not localized to a VPS location that contains the target node specified for the graph operation. | | static TargetNodeNotFound | VpsGraphOperationError | Code returned when the VPS location that the device is localized to does not contain the target node specified for the graph operation. | ---
