Configuring ConvertPdfService: 1.2

Hi,

I am getting following error while configuring ConvertPdfService: 1.2 as a watch folder:

location ---- Reason of failure is-----Cannot coerce object: *.tif of type: java.lang.String to type: class com.adobe.livecycle.convertpdfservice.client.ToImageOptionsSpec

Cannot coerce object: *.tif of type: java.lang.String to type: class com.adobe.livecycle.convertpdfservice.client.ToImageOptionsSpec

I want to convert PDF to TIFF  but not sure what should be the values of below configurations for achiving the same.

Please help to advise on the same.
