- 当前 Bug 的表现（可附上截图）

- 预期表现

- 复现路径

- 提供一个最简复现 Demo

let tempFilePath = cc.game.canvas.toTempFilePathSync({

x: 0,

y: 0,

width: 720,

height: 1280,

destWidth: 500,

destHeight: 400

});

cc.log(tempFilePath);

let fw = wx.getFileSystemManager();

let res = fw.copyFileSync(tempFilePath, `${wx.env.USER_DATA_PATH}/shotScreen.png`);

cc.log(res);

cc.log(`${wx.env.USER_DATA_PATH}/shotScreen.png`);

模拟器上log都有打印，res为空，其他有值

实机上（米max报错）
