调研方向

从 AutogenView.vue 中的 beforeRouteLeave 开始,那里会取消 listVirtualMachines;再看 ProjectMenu.vue 中的 changeProject,它会触发路由切换。然后检查 request.js,取消逻辑和全局错误处理程序都在那里,弄清楚为什么带有 ERR_CANCELED 的 CanceledError 会弹出“Unable to reach the management server”通知。完成的标准是:主动取消的请求被静默忽略,而真正的网络故障仍然显示该通知。

描述

bug
problem

After upgrading to 4.20.3.1, the UI shows an error notification every time I switch from a project view to the default view while the Instances page is open:

"canceled – Unable to reach the management server or a browser extension may be blocking the Network request."

This is not a network issue: nothing is logged in management-server.log at that moment, and the same error is shown when connecting to the management server directly (no reverse proxy). The instance list itself loads correctly after the switch.

The browser console shows that the in-flight listVirtualMachines request is intentionally cancelled by the UI on route change, and the resulting CanceledError is treated as a network failure and reported to the user:

AutogenView.vue:658 DEBUG - Due to route change, ignoring results for any on-going API request listVirtualMachines
CancelToken.js:58 Uncaught (in promise) i {message: 'canceled', name: 'CanceledError', code: 'ERR_CANCELED', ...}
cancel @ request.js:196
beforeRouteLeave @ AutogenView.vue:659
...
push @ vue-router.esm-bundler.js:2986
changeProject @ ProjectMenu.vue:92

versions

ACS: 4.20.3.1 (upgraded from [previous version])
Management servers: 3 nodes, Ubuntu 24.04, behind HAProxy (also reproducible when bypassing the proxy)
Browsers/OS: reproducible in multiple browsers and operating systems Chrome/Windows 11, Firefox/Ubuntu

The steps to reproduce the bug
  1. Log in to the UI and select a project in the project selector.
  2. Open Compute > Instances (the listing is shown for the project).
  3. While on the Instances page, switch from the project view to the default view.
  4. The error notification appears.
What to do about it?

The in-flight listVirtualMachines request is cancelled in beforeRouteLeave (AutogenView.vue) when the project is changed (changeProject in ProjectMenu.vue). The resulting CanceledError (ERR_CANCELED) is not filtered out and reaches the global error handler, which shows the "Unable to reach the management server..." notification.

A deliberately cancelled request should probably be silently ignored instead of being reported as a network error.
