So my setup work if I dont use mantra node or ropfetch node in tops. I have verified that as you can se in the pictures. What is the correct setup to have mantra and ropfetch work?

Your .hip file was last saved in H19.0, but you're loading it in an H19.5 version of Hython. It looks like there are some slight parameter differences on the Mantra node that are causing load warnings. By default, hou.hipFile.load(..) treats warnings as an error, but you an fix that by passing ignore_load_warnings=True into the load function as described here: https://www.sidefx.com/docs/houdini/hom/hou/hipFile.html#load [www.sidefx.com]

If you load your file in H19.5 and resave it that'll also clear up the warnings on future loads.

thank you so much, that solved it for me.
