Error With GRIP

Hello, my team and I are using GRIP for our vision processing. When using the Find Contours module, we have encountered this error:

java.lang.RuntimeException: src\contours.cpp:198: error: (-210) [Start]FindContours supports only CV_8UC1 images when mode != CV_RETR_FLOODFILL otherwise supports CV_32SC1 images only in function cvStartFindContours

Does anyone know a solution to this?
Thanks in advance.
