First of all, it can only trace local raster files. So don't try to trace OpenStreetMaps.
Second, check what color space your image has. For more detail see "What image can it trace" section in the README. Changes are, this will help.
It this isn't helping, check in in this issue and we'll figure out what's going on with your layer.
I have been trying to use Raster Tracer to vectorize roads and rivers from raster images. I tried using as raster both my own raster images and also Open Street Maps QGIS tiles. None of works, giving the error:
I am using the most recent QGIS, 3.26.1-Buenos Aires. And I have reinstalled Raster Tracer.
Any ideas?
