I am trying to search for records in account.move.line by partner_ids. I'm first searching the res.partner table and then  passing the ids from that search into the account_move_line_ids search but I get an error "INVALID LEAF". Can someone help me understand whats going wrong?

supplier_ids = sock.execute( dbname, uid, pwd, 'res.partner', 'search', [( 'supplier', '=', True ), '|', ( 'active', '=', True ), ( 'active', '=', False )] )
account_move_line_ids = sock.execute( dbname, uid, pwd, 'account.move.line', 'search', [( 'partner_id', 'IN', supplier_ids )] )
