Can dbOpenCellViewByType Open a Config View?

I am trying to check that a schematic and config view exists for a specific cell and display a custom error message if it doesn't exist.  However the dbOpenCellViewByType call I am using seems to work for the schematic view but not for the config view.  Is there a better way of checking for the existence of a config cell view?  (or for the schematic for that matter)

Here is the code I have tried:  ( The first check on the schematic does not cause an error, whereas the config check does.  Both the schematic and the config views exist.

; Check that the test bench schematic view exists
schemCellObj = dbOpenCellViewByType("pk1126_sky77366_5_CR_mayberc" "pk1126_demo_TB" "schematic")
if(schemCellObj == nil
then
error("The schematic view must be created before the ADEXL view is imported. Please makse sure the testbench schematic and config views have been created and try importing the adexl view again.")
else
dbClose(schemCellObj));

; Check that the test bench config view exists
configCellObj = dbOpenCellViewByType("pk1126_sky77366_5_CR_mayberc" "pk1126_demo_TB" "config")
if(configCellObj == nil
then
error("The config view must be created before the ADEXL view is imported. Please makse sure the testbench schematic and config views have been created and try importing the adexl view again.")
else
dbClose(configCellObj));

Here is the error I get:

*WARNING* (DB-270211): dbOpenCellViewByType: Failed to open cellview (pk1126_demo_TB config) from lib (pk1126_sky77366_5_CR_mayberc) in 'r' mode because cellview does not exist, or cellview type is not recognized by dbOpenCellViewByType.
