一、该问题的重现步骤是什么？

1. 启动图片.png

2. 在 http://localhost:1888/#/flow/deploy 中进行上传请假流程图片.png

3.流程设计器的后台日志如下:2020-09-29 14:41:18.177 ERROR 7440 --- [ XNIO-1 task-17] io.undertow.request                      : UT005023: Exception handling request to /app/rest/import-process-model

二、你期待的结果是什么？实际看到的又是什么？

期待正常进行流程部署.实际无法进行流程部署.

三、你正在使用的是什么产品，什么版本？在什么操作系统上？

BladexAvue联合版本 2.5.1 Release 在Win10操作系统

四、请提供详细的错误堆栈信息，这很重要。

五、若有更多详细信息，请在下面提供。

我测试了cloud和boot两个版本都没遇到这个问题，没法重现不太好找原因。你用master分支原生的2.6.0版本跑一下，然后到这个方法打个断点，调试下看看哪一步会报错。如果找到可以重现到步骤就发我，我跟着步骤去调试
