Tool/software:
Hi team,
I'm working on SDK 08_02_00_05(Linux+RTOS).
When testing a application, I'm facing the below error log.

}
When I dumped obj->colorConvRGBNV12Obj.dst_image_arr the output is not expected but it's not NULL. Attaching the dump below.
But when the same is passed to app_create_graph_ldc function which is the next node, I'm facing the error.
output image is NULL in ldc
62.038711 s: VX_ZONE_ERROR:[vxSetParameterByIndex:228] Supplied value was not actually a reference
62.038721 s: VX_ZONE_ERROR:[vxSetParameterByIndex:305] Specified: parameter[7] type:00000000 => (nil)

62.038739 s: VX_ZONE_ERROR:[ownReleaseReferenceInt:307] Invalid reference
62.038746 s: VX_ZONE_ERROR:[vxGetStatus:713] Reference is NULL
What could be the reason for this behaviour? How to resolve this?
