Baked texture export error.

[Sk3in]

When I try to export the baked textures, I get this error. Any idea how to fix it? I'm in Blender 4.2.3 LTS

Python: Traceback (most recent call last): File "C:\Users\Skein\AppData\Roaming\Blender Foundation\Blender\4.2\extensions\blender_org\ucupaint\image_ops.py", line 706, in execute image.save_render(path, scene=tmpscene) RuntimeError: Error: Image 'Ucupaint Material Color' does not have any image data

Thanks.
