I will also say that another (possibly simpler) way of solving this issue is just to use OpenStudio 2.5.0.
The newer versions of OpenStudio have a lot of changes made to them, which makes them incompatible with the versions of Honeybee components from a few months ago (hence @SaeranVasanthakumar 's suggestion to update the components)
I will also add that OpenStudio 2.6 and OpenStudio 2.7 have bugs in them that can mess up a few specific workflows (for example, you cannot apply certain analysis periods to the simulation in OS 2.7).
