Additional context
i am completely new to this bug reporting. i am trying to contribute to Natron since i love it. i want to do an edge detection on my text using the sobel filter and i get advice from deepseek that i can use the convolve filter. when i connect it it gives that error i just pasted on top. previously other nodes have given me same error from the gmic filters. i am not sure if this is the right way to ask for help. thank you.
