TypeError: Cannot read property ‘elem‘ of undefined at M (VM4401 WAService.js:2) at VM4401 WAService.js:2 at VM4401 WAService.js:2 at n (VM4399 asdebug.js:1) at e.exports.<anonymous> (VM4399 asdebug.js:1) at VM4399 asdebug.js:1 at Array.forEach (<anonymous>) at WebSocket._ws.onmessage (VM4399 asdebug.js:1)
当前的基础库版本是2.10.1 ，只需要将基础库版本改为2.10.0即可
