Anypoint Studio ERROR 尽管一切正常
Anypoint Studio ERROR despite everything working correctly
我在 Mule Soft 中创建了端点，它包含来自 3 个单独的 APIs（2 个 REST 和 1 个 SOAP）的数据，但尽管它工作正常 return 一个错误：
ERROR 2021-12-22 00:24:23,483 [[MuleRuntime].uber.04: [projekt_isi].Found_course_response.BLOCKING @3d5f454f] [processor: Found_course_response/processors/6; event: 1dd95df0-62b5-11ec-902a-d481d75d7926] org.mule.soap.internal.generator.attachment.AttachmentResponseEnricher: Could not close XMLEventWriter
因为这个请求需要很长时间，所以我猜是这个错误导致了它，但我在互联网上发现的是 XML 转换的问题，据说已经解决了。你遇到过这样的问题吗？这很奇怪，尤其是因为我得到了正确的 JSON 响应，其中包含来自 REST API 的 JSON 响应以及来自 SOAP API 的转换后的 XML 响应。
流程如下所示：
编辑：这里要求的是整个错误：

尝试将 Web 服务使用者从当前版本 1.6.6 升级到最新版本 1.6.7。它应该解决该错误消息的打印。
我在 Mule Soft 中创建了端点，它包含来自 3 个单独的 APIs（2 个 REST 和 1 个 SOAP）的数据，但尽管它工作正常 return 一个错误：
ERROR 2021-12-22 00:24:23,483 [[MuleRuntime].uber.04: [projekt_isi].Found_course_response.BLOCKING @3d5f454f] [processor: Found_course_response/processors/6; event: 1dd95df0-62b5-11ec-902a-d481d75d7926] org.mule.soap.internal.generator.attachment.AttachmentResponseEnricher: Could not close XMLEventWriter
因为这个请求需要很长时间，所以我猜是这个错误导致了它，但我在互联网上发现的是 XML 转换的问题，据说已经解决了。你遇到过这样的问题吗？这很奇怪，尤其是因为我得到了正确的 JSON 响应，其中包含来自 REST API 的 JSON 响应以及来自 SOAP API 的转换后的 XML 响应。
流程如下所示：
编辑：这里要求的是整个错误：
