interesting, your installation seems to have worked. Is the problem persistent? Meaning that it doesn’t happen just once in a while but consistently every time you run viktor-cli start.
In that case I would suggest (based on this post) to run viktor-cli configure one time. You can just leave all the answers to the prompts that follow blank as it will have saved the correct values already.
Another thing @bvanderhulst just pointed out to me is that you’re storing your files from a OneDrive folder. You could try to put them in a local directory and running the app from there.
Let me know if that helps!
