Java toSpatialDatabaseRecordList生成NullPointerException

我们在使用neo4j的java插件时遇到了一个问题。直到今天，我们在GeoPipeline上使用toSpatialDatabaseRecordList方法都没有问题。我们刚刚纠正了一些错误，现在我们在方法调用中得到了一个NullPointerException

代码如下：

try (Transaction tx = graphDb.beginTx()) {
    geoPoints = GeoPipeline
        .startNearestNeighborLatLonSearch(layer, point, radius)
        .toSpatialDatabaseRecordList();
    tx.success();
}

你知道如何处理这个问题吗？这是数据问题吗

问候,
