loader（0.7.0）导入数据出错，后端是scylladb

[Blessness]

使用loader的example目录下文件导入测试，出现如下错误：

schema.groovy 配置文件信息如下：

schema.propertyKey("name").asText().ifNotExist().create();
schema.propertyKey("age").asInt().ifNotExist().create();
schema.propertyKey("city").asText().ifNotExist().create();
schema.propertyKey("weight").asDouble().ifNotExist().create();
schema.propertyKey("lang").asText().ifNotExist().create();
schema.propertyKey("date").asText().ifNotExist().create();
schema.propertyKey("price").asDouble().ifNotExist().create();

schema.vertexLabel("person").properties("name", "age", "city").primaryKeys("name").ifNotExist().create();
schema.vertexLabel("software").properties("name", "lang", "price").primaryKeys("name").ifNotExist().create();

schema.indexLabel("personByName").onV("person").by("name").secondary().ifNotExist().create();
schema.indexLabel("personByAge").onV("person").by("age").range().ifNotExist().create();
schema.indexLabel("personByCity").onV("person").by("city").secondary().ifNotExist().create();
schema.indexLabel("personByAgeAndCity").onV("person").by("age", "city").secondary().ifNotExist().create();
schema.indexLabel("softwareByPrice").onV("software").by("price").range().ifNotExist().create();

schema.edgeLabel("knows").sourceLabel("person").targetLabel("person").properties("date", "weight").ifNotExist().create();
schema.edgeLabel("created").sourceLabel("person").targetLabel("software").properties("date", "weight").ifNotExist().create();

schema.indexLabel("createdByDate").onE("created").by("date").secondary().ifNotExist().create();
schema.indexLabel("createdByWeight").onE("created").by("weight").range().ifNotExist().create();
schema.indexLabel("knowsByWeight").onE("knows").by("weight").range().ifNotExist().create()

将index部分删除后，执行导入依然报错：
`schema.propertyKey("name").asText().ifNotExist().create();
schema.propertyKey("age").asInt().ifNotExist().create();
schema.propertyKey("city").asText().ifNotExist().create();
schema.propertyKey("weight").asDouble().ifNotExist().create();
schema.propertyKey("lang").asText().ifNotExist().create();
schema.propertyKey("date").asText().ifNotExist().create();
schema.propertyKey("price").asDouble().ifNotExist().create();

schema.vertexLabel("person").properties("name", "age", "city").primaryKeys("name").ifNotExist().create();
schema.vertexLabel("software").properties("name", "lang", "price").primaryKeys("name").ifNotExist().create();

schema.edgeLabel("knows").sourceLabel("person").targetLabel("person").properties("date", "weight").ifNotExist().create();
schema.edgeLabel("created").sourceLabel("person").targetLabel("software").properties("date", "weight").ifNotExist().create();`

Vertices has been imported:Exception in thread "main" java.lang.IllegalStateException: The id field can't be empty or null when id strategy is CUSTOMIZE

但scheme中并没有将VertexId使用 CUSTOMIZE 策略。

期待回复~

原因是之前创建过一样的scheme，但我在数据库中将数据删除了，但server有缓存，重启server后导入成功。
