"fn invoke pythonapp pythonfn" failed follow the example steps

[hb-lee]

When I follow the example steps to build the pythonapp, it failed with "Error invoking function. status: 500 message: internal server error" when I invoke the pythonfn. The fn server messages show:

Can anyone give any suggestion?
