Hi friends,

The node-red stream is as follows.  
How do I update with the code specified in "Set message payload function". I can insert insert with the same code, but I can't update the current record.

How do I update the function code?

**Set message payload function**  
msg.payload ={"\_id": msg["\_id"]};  
var msg = {  
'collection' : 'cihazlar',  
'operation': 'updateOne',  
'payload': {  
// '\_id': '5c41cacec3bcb01b705c45b9',  
'nodebolge': 'area',  
'nodename': 'nameField',  
'nodeabone': 'device3',  
'endeks': 'index'  
}  
};  
return msg;

**Flow**
