我有以下 DMN，它具有文本值作为输入，并且具有仅使用特定值作为枚举约束的约束。

这在 Trisotech 中测试时工作正常。但是当与服务集成时，它会抛出如下所述的错误。

2021-09-20 19:07:48.943 ERROR --- [ main] o.k.d.core.ast.DMNDTExpressionEvaluator : income.creditRating='EXCELLENT' does not match any of the valid values "EXCELLENT", "GOOD", "BAD", "POOR" for decision table 'ActionableDecision'.

我在服务中使用以下版本的 kie。有人可以提出问题的原因吗？

<dependency>
      <groupId>org.kie</groupId>
      <artifactId>kie-dmn-core</artifactId>
      <version>7.57.0.Final</version>
</dependency>

示例项目可以在这里找到

您需要分享有关如何调用 Drools DMN 引擎的更多详细信息；是通过 Kogito 还是 Kie 服务器？您是否使用 Drools 作为嵌入式 modre 中的库，您是否使用 Kogito API、Kie v7 API、Kie Server Client (Java) API 等。

这是因为如下图所示，它基于 Kogito 并利用 Drools DMN 引擎，一切正常且符合预期： 演示

因此，您与引擎交互的特定方式一定出了问题。
