The problem is your SetpointManager:MixedAir called Mixed Air Temp 2 which is illegal, it's missing the Reference Setpoint Node Name and the Fan Outlet Node Name to be valid.
Whether you meant to use this object in the first place or not is only known to you, and since we don't have the required info from your input file to tell for sure how it should be structured, I can only give you some guidance/placeholders as to how it should be used:
SetpointManager:MixedAir,
Mixed Air Temp 2, !- Name
Temperature, !- Control Variable
<< Name of your Air Loop Outlet Node >>, !- Reference Setpoint Node Name
Node 71, !- Fan Inlet Node Name
<< Name of your Fan Outlet Node >>, !- Fan Outlet Node Name
<< Name of your Mixed Air Node >>; !- Setpoint Node or NodeList Name

EDIT: reading your question again, it seems that even though you tagged this question with energyplus, I think you're using OpenStudio.
If you cannot find a MixedAir setpoint anywhere in your model, maybe it got orphaned. It would be useful if you could share your OpenStudio *.osm file so we can take a deeper look.
You could also try to the open your .osm in a text editor, and search for Mixed Air Temp 2 to see if this present in the OpenStudio file already (orphaned), or whether it's created when the model is ForwardTranslated to the E+ IDF file. (Or use the ruby bindings, spm = model.getSetpointManagerMixedAirByName("Mixed Air Temp 2").get,e tc.)
