读取角色当前自定义部门集失败: %w

Error message

读取角色当前自定义部门集失败: %w

What it means

Before applying a new data scope, the setter reads the role's current custom department set from `/authority/getDataScopeDepts` to build a before/after diff. Failure of that GET (wrapped with %w) aborts the operation so the change report stays accurate. The root cause is preserved in the wrapped error.

Solutions

1. Check the wrapped error: a 404 means the gva server version lacks the endpoint — upgrade the server
2. Refresh authentication if the error indicates 401/403
3. Verify network connectivity to the upstream gva host
4. Retry the operation once connectivity/auth is restored

Example fix

// before
beforeDeptsResp, err := getUpstream[[]uint](ctx, "/authority/getDataScopeDepts", query)
// after
if err != nil {
    log.Printf("getDataScopeDepts failed (authorityId=%d): %v", authorityID, err)
    return nil, fmt.Errorf("读取角色当前自定义部门集失败: %w", err)
}

// ensure auth is valid before the read
if !tokenFresh(mcpToken) {
    refreshToken()
}

before, err := readCurrentDepts(ctx, authorityID)
if err != nil {
    if isAuthError(err) {
        refreshToken()
        before, err = readCurrentDepts(ctx, authorityID)
    }
    if err != nil {
        return err
    }
}

When it happens

Trigger: Upstream GET /authority/getDataScopeDepts fails due to network issues, 401/403 auth, or the endpoint being unavailable in an older gva server version.

Common situations: Expired JWT; older server build lacking the getDataScopeDepts route (404); temporary network partition between MCP server and gva backend.
