It looks like your version of the redfish package is out of date; version 2.0.8 added some helpers for task management. We also updated the requirements.txt file to reflect that (currently shows it needs to be 2.1.0 or higher).

Could you please try running pip3 install -r requirements.txt and try it again?

[gkeishin]

@mraineri sure.. let me do those and check..

Thanks! Would you be able to provide the computer system resource for "1318ECA"? I'm guessing it doesn't have a "PowerState" property.

I think I see the problem; there's an assumption the test is doing right now where it assumes the URI of the systems it finds follow the pattern "/redfish/v1/System/{SystemId}", where {SystemId} is the Id property of the system. This was a rule added in Redfish spec version 1.6.0, but older implementations can't be assumed to follow this.

I'm guessing at this point it's doing a "GET" on "/redfish/v1/Systems/1318ECA", which will result in a 404. However, I'd expect it to not get a JSON decoding error; a 404 should still be returning a JSON response.

What is provided as the response if you try to go to /redfish/v1/Systems/1318ECA? There is definitely some cleanup and error checking that can be done to make this more helpful, but it would be good to know so I can try to simulate the condition while making improvements.

I made a branch with a fix for the issue. If you can please try it out for me and let me know how it goes.

[gkeishin]

Awesome @mraineri .. Will do in few... Will keep posted
