Why would I get this error, it's a searchable field, according to the MetaData:
http://gfbr.rets.paragonrels.com/rets/fnisrets.aspx/GFBR/search?Class=ActiveAgent&SearchType=ActiveAgent&QueryType=DMQL2&Count=1&StandardNames=0&Format=COMPACT-DECODED&Limit=NONE&Query=(U_AgentID=0%2b),(U_UpdateDate=2020-06-18T19:18:00%2b)&OrderBy=U_AgentID&Offset=1
'Unknown Query Field [U_UpdateDate].'
