```

The above is a test code, The following is the **msg.error** information  
 ![1675220530662](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/3/8/38552dfcdbcb5ad3813d4d7df67520f2af6e6365.png)

My problem is that when there are many codes in the function, it is difficult to accurately locate the specific error location only by the existing error information. Is there any way to display the stack information?

Pls help, Thanks！
