Removing bypass in a loop to convert to series arrangement

edit

Hi Everyone, I am working off the example file on ground heat exchangers (GSHP-GLHE). I have made modifications to remove the bypass in the condenser supply side loop so that its a simple series arrangement with: 1) Constant speed pump 2) Ground Heat Exchanger But I get the following error. If a loop does not have any mixers or splitters does EnergyPlus still need a Connector list? If so what should I specify?

Program Version,EnergyPlus, Version 9.3.0-baff08990c, YMD=2020.06.07 19:39,
** Severe  ** <root>[CondenserLoop][Condenser Loop] - Missing required property 'condenser_side_connector_list_name'.
