Local server won't work using netlify CLI

Hey there!, Am using sveltekit framework for my app, trying to integrate the netlify functions into it, so when I try to test and develop it using netlify CLI my initial app or landing page shows function not found on my local server on port 8888 , But my functions endpoint does work normally and totally well


Above image is what I am actually experiencing

Not sure if CLI is tested to work with github.dev. In any case, there’s no help we can provide with the given description. Provide a reproduction so we can check.
