获取菜单列表失败: %w

Error message

获取菜单列表失败: %w

What it means

After the batch-size check, the assigner fetches the full base-menu tree via POST `/menu/getMenuList` to validate IDs, complete parent chains, and build write-back payloads. Any failure of that upstream call is wrapped with this message. Without the menu list no assignment can proceed.

Solutions

1. Check the wrapped cause for network vs upstream API error
2. Confirm the gva server is running and the menu API responds (curl /menu/getMenuList)
3. Refresh auth token if 401
4. Inspect server logs for errors in menu listing (often DB-related)

Example fix

// before
allResp, err := postUpstream[[]system.SysBaseMenu](ctx, "/menu/getMenuList", map[string]any{})
if err != nil {
    return nil, fmt.Errorf("获取菜单列表失败: %w", err)
}
// after
allResp, err := postUpstream[[]system.SysBaseMenu](ctx, "/menu/getMenuList", map[string]any{})
if err != nil {
    log.Printf("getMenuList failed: %v", err)
    return nil, fmt.Errorf("获取菜单列表失败: %w", err)
}

// health-check the menu endpoint before assignment
resp, err := postUpstream[[]system.SysBaseMenu](ctx, "/menu/getMenuList", map[string]any{})
if err != nil || len(resp.Data) == 0 {
    return fmt.Errorf("menu source unavailable")
}

err := retry(3, backoff, func() error {
    _, err := assignMenus(ctx, authorityID, menuIDs)
    return err
})

When it happens

Trigger: POST /menu/getMenuList fails: server unreachable, 401 on expired token, route missing, or server error while listing menus.

Common situations: gva backend down or restarting; JWT expired mid-session; database connectivity issue on the server side making menu listing fail; wrong upstream base URL.
