Color Erosion Node Export Blank?

Hello everyone! I might be missing something obvious, but I can’t figure anything out just yet. I’ve been using GAEA to export overlays for Worldpainter, a software to build Minecraft maps. It uses PNG and TIFFs for overlays, and up until yesterday, I was able to use the color erosion node to export a PNG image that I could then use as a mask in Worldpainter. This morning, I decided to use a color image from Worldpainter as a base texture to then use the color erosion node and re-export to Worldpainter, but no matter what I do, the final exported image from the node is completely blank. I’ve changed export resolution, deleted and re-added the nodes, and even completely remade the project file, but I can’t get it to work. Any other suggestions?

Can you please share the screenshot of the graph setup?
