I'm modeling water to air heat pump in open studio but even though I can see the nodes in the loop tab, simulation gives error like following:

** Severe  ** IP: IDF line~121718 Error detected in Object=COIL:COOLING:WATERTOAIRHEATPUMP:EQUATIONFIT, name=WTR-TO-AIR HP CLG COIL 60
   **   ~~~   ** Field [Water Inlet Node Name] is required but was blank
   ************* IDF Context for following error/warning message:
   ************* Note -- lines truncated at 300 characters, if necessary...
   *************  121716 Coil:Cooling:WaterToAirHeatPump:EquationFit,
   ************* indicated Name=Wtr-to-Air HP Clg Coil 60
   ************* Only last 3 lines before error line shown.....
   *************  121717   Wtr-to-Air HP Clg Coil 60,             !- Name

   *************  121719   ,                                      !- Water Outlet Node Name

Also I have a fatal error which is:

** Severe  ** IP: Possible incorrect IDD File
   **   ~~~   ** IDD Version:"IDD_Version 8.4.0"
   **   ~~~   ** Version in IDF="8.4" not the same as expected="8.4"
   **   ~~~   ** Possible Invalid Numerics or other problems
   **  Fatal  ** IP: Errors occurred on processing IDF file. Preceding condition(s) cause termination.

Has anyone encountered this type of error before?
