Hello @sou and welcome to the forums! I moved your post over here to a new thread so we could close the other one - it’s 2 years old and had already been resolved, but not closed.
The error is stating that your threat raster, railway_2023.tif has pixel values that are not in the range of 0-1. If you correct this issue in your GIS and try re-running the model, this will likely resolve the issue.
Let us know if you have any further questions!
