Hi @Vijaya,
I believe this is due to a known error discussed here, which we’re planning to address soon. If this is the same problem, it is caused by the mask not being scaled correctly to the range of [0,1]. Can you check the mask that was input to the job in the mask_refine slot has the correct range, and that values are between [0,1] and not some other range? If the mask is alright, can you then follow the GIF posted here to connect the inputs?
Best,
Michael
