The vue3 project has a module that uses the el-drawer drawer. When the drawer is opened and then closed, an error will be reported when other modules are opened

The function of the project is intact, that is, after the drawer is closed, and then click on other pages, each page will report this error
On the Internet it is said to be the problem of using v-if, but I didn't use it
On the Internet it is also said to be the problem of rendering, but I added :destory-on-close to no avail,
The most important thing is that I have no problem locally, and there is no problem in the simulated test environment, but there is a problem once deployed to the test environment.
If you click to switch a page that is not the current sub-application, it should trigger the unmount of the sub-application
You can try to destroy the vue instance when the sub-application is unmount to see if it works
I have no problem locally, and there is no problem in the simulated test environment, but there is a problem as soon as it is deployed to the test environment
Is it possible that the development environment and the test environment are packaged inconsistently?
You look in and see who xxx.getAttribute reports the error xxx, think about why it is null, whether it is overwritten or caused by the incompatibility of vue2vue3api calls.Best to post a screenshot
