SQL Query

My BI software is sending the following query to SQL server.

SELECT [SalesImportHistoryV2].[CLASS_DESC],SUM((Case
 When SalesImportHistoryV2.RSID_TYPE = 'S'
 Then SalesImportHistoryV2.RSID_EXTENDED
 Else NULL
 End)) as FLD0000005 ,Min(COALESCE('',''))

End
End] = '1700 West'
 group by [SalesImportHistoryV2].[CLASS_DESC]



I get the following error:
Msg 103, Level 15, State 4, Line 7
The identifier that starts with 'Case
When gldv_alt_div_n in ('1120', '1125', '1170', '1203', '1207', '1209', '1213', '1214', '1215', '1218', '1260', '1267', '12' is too long. Maximum length is 128.


I've used this case statement numerous times for other reasons, why would it give me this error this time?
