Error with sysspatial.tessellate_index

Error with sysspatial.tessellate_index

 I am trying to execute sysspatial.tessellate_index but getting following Error: 

*** Failure 7504 in UDF/XSP/UDM SYSSPATIAL.tessellate_index: SQLSTATE 04000: Inconsistency between object coordinates and universe coordinates in TessellationEngine
Statement# 1, Info =0


This is how I am calling  this:

INSERT INTO customers_idx
SELECT
id
,sysspatial.tessellate_index (
location.ST_X(),location.ST_Y(), location.ST_X(), location.ST_Y()
,-180, 0, 0, 90
,1000,1000
,1,0.01,0)
FROM customers


Please help me understand the error and the fix.

Below is the table definition (if you like to know):

CREATE SET TABLE PP_MONITOR.customers ,NO FALLBACK ,
NO BEFORE JOURNAL,
NO AFTER JOURNAL,
CHECKSUM = DEFAULT,
DEFAULT MERGEBLOCKRATIO
(
id DECIMAL(18,0),
location SYSUDTLIB.ST_Geometry)
PRIMARY INDEX ( id );
