sv3d_conditioning node cant take input thats used rembg

[webcoderz]

i have a workflow where i do a txt2img pipeline with sdxl turbo, if i use rembg to remove the background from the image it works,

but once i put this in front of the sv3d and input the rembg image into the input mage of sv3d_conditioning , it complains about tensor size and errors

"The size of tensor a (4) must match the size of tensor b (3) at non-singleton dimension 1"

my guess is here:

encode_pixels = pixels[:,:,:,:3]

Probably shouldn't slice down to 3 channels from 4? I tried multiple diff nodes in front of it and same issue each time
