“invalid LRS segment” when querying an Oracle Spatial DB

I have a table of GIS segments in an Oracle Spatial database. I'm using C# and ODP to connect to the database. For a given measure from the start of a segment, I want to find the GPS coordinates for that point. I'm running the following query:

select g.geom.sdo_ordinates ord_array from
*(select sdo_lrs.locate_pt(shape,0.02,0) as geom from test_schema.test_table*
where route='ABC' and segmentnum='101.1') g

where shape is of type SDO_GEOMETRY. I'm getting the following error:

ORA-13331: invalid LRS segment

Is there a problem with how I'm passing shape to locate_pt()? The Oracle Spatial documentation says the argument should be SDO_geometry, so that seems ok.
