Error creating NPM package with SvelteKit

Question

Let's go. I created the package and am trying to test it locally. I ran the npm run package, and installed it locally with npm install <path>. When installing the package I have the following problems: When inserting the forward slash (/) to access a submodule, instead of displaying the available modules, it displays a list of the entire directory where I am working on the package, instead of only displaying the path to the submodule. In VSCode, if I add svelte-base-app/dist/auth it doesn't display any error but the code doesn't work. When changing the import to svelte-base-app/auth, VSCode displays an error (Cannot find module svelte-base-app/auth), but the code works normally. My packge.json:
