Python2.7: TypeError: Cannot mix str and non-str arguments

[Lucas Alvares Gomes]

Running python-redfish on Python2 is raising the following error as part of the connect() method: TypeError: Cannot mix str and non-str arguments.

It works fine on Python3.5 tho

Hello Lucas,

First thanks for all the bug reports. I will try to look at them ASAP.
Can you please just let me know the simulator and python-redfish release you used.
This will probably help me to reproduce the bug.

[Lucas Alvares Gomes (lucasagomes)]

Hi Rene,

I've used the version 1.0.0 (DSP2043) downloaded from https://www.dmtf.org/standards/redfish

Direct link: https://www.dmtf.org/sites/default/files/standards/documents/DSP2043_1.0.0.zip

[Uggla (rene-ribaud)]

OK thanks. What about python-redfish ?

FYI, I have not tested against simulator v1.0. So that may explain I have not seen the bug so far.

[Lucas Alvares Gomes (lucasagomes)]

Hi Renne,

The python-redfish was installed from source, master branch HEAD.
