Hello there,
when I trying to extract "msg" field generated by example program "demo-tracef"
with python binding , I got following error message:
Traceback (most recent call last): File "data.py", line 46, in <module>
sequence = event["msg"] File
"/usr/local/lib/python3.3/site-packages/babeltrace.py", line 806, in
__getitem__ return field.value File
"/usr/local/lib/python3.3/site-packages/babeltrace.py", line 1279, in value
value.append(evDef.value)AttributeError: 'NoneType' object has no attribute
'value'
but everything works fine with babeltrace cmd[15:42:32.322566678]
