How to enable stacktrace?

[pinksawtooth]

I want to use TACO.
But cuckoo 2.0 can not record stack trace.
How did you record stack trace?

The log of cuckoo is as follows

                       "category": "file",
                        "status": 1,  
                        "stacktrace": [], 
                        "api": "NtWriteFile",
                        "return_value": 0,
                        "arguments": {
                            "buffer": "AAAAAAAA", 
                            "file_handle": "0x00000110",
                            "offset": 0
                        }, 
                        "time": 1495589729.518876,
                        "tid": 2616,
                        "flags": {}
                    },
