请问有人知道怎么解决吗？
更新
我尝试调试问题，我会删除我添加的每个三元组，直到没有问题出现，
我在删除 serviceWithoutReasoner 的三元组时发现它有效，但我不知道这些三元组有什么问题以及如何解决它们
Update2
听说fuseki 2.3不支持多服务，但我不确定
更新 3
正如 @Joshua Taylor 所建议的，我尝试了 fueseki 2.0.0 上的配置并且它运行良好，这意味着在 fuseki 2.3 中，他们停止使用 mutil 服务，这很容易证明这不是我的错误。
documentation page 表示每个文件 只能有一项服务。所以你可能有多个服务，但你需要多个配置文件，或者使用单个服务配置文件。来自文档（添加了重点）：
The data services configuration can come from:
- The directory FUSEKI_BASE/configuration/ with one data service assembler per file (includes endpoint details and the dataset description.)
- The system database. This includes uploaded assembler files. It also keeps the state of each data service (whether it's active or offline).
- The service configuration file. For compatibility, the service configuration file can also have data services. See below.
- The command line, if not running as a web application from a .war file.
即便如此，旧的配置文件也应该“正常工作”。来自同一页面：
Compatibility with Fuseki 1 configuration
Configurations from Fuseki 1, where all dataset and server setup is in
a single configuration file, will still work. It is less flexible (you
can't restart these services after stopping them in a running server)
and user should plan to migrate to the new layout.
To convert a Fuseki 1 configuration setup to Fuseki 2 style, move each
data service assembler and put in it's own file under
FUSEKI_BASE/configuration/
就是说，也许您想要一个带推理的命名图和一个不带推理的命名图，两者都在同一个数据集中。我认为您不需要为此提供多项服务，只需要数据集中的多个图表。
我正在使用这个配置并且它正在工作
