Wasn't able to find anything around this error. Hope someone could help me out. I've got a Next.js 13 instance running in Node v19.7.0. When I tried `npx @slicemachine/init` in the directory, I got the following error: ```auto Slice Machine → Init command started ℹ We collect telemetry data to improve user experience. Learn more: https://prismic.dev/slice-machine/telemetry ✔ Detected framework Next.js 11-13 and package manager npm ✔ Began core dependencies installation with npm ... (running in background) ✖ Logging in to Prismic... → Prismic authentication state is invalid. UnexpectedDataError: Prismic authentication state is invalid. at PrismicAuthManager._readPersistedAuthState (/Users/x/.npm/_npx/b6923b01b288b666/node_modules/@slicemachine/manager/dist/auth/PrismicAuthManager.cjs:262:13) at async PrismicAuthManager.checkIsLoggedIn (/Users/x/.npm/_npx/b6923b01b288b666/node_modules/@slicemachine/manager/dist/auth/PrismicAuthManager.cjs:160:23) at async Task.task (/Users/x/.npm/_npx/b6923b01b288b666/node_modules/@slicemachine/init/dist/SliceMachineInitProcess.cjs:221:30) ``` I've tried Prismic Logout & Login, Reinstalling Prismic-cli, or manually installing slice-machine, it keeps throwing the same error. Has anyone run into the same problem? Appreciate any help!! ---

Hi @motmotstudiostudio, Thanks for your patience. I reproduced the issue when I deleted the cookies attribute in the `~/.prismic` file. I suggest you delete the `~/.prismic` file and ran this command `npx @slicemachine/init@latest` Let me know if this works for you. Thanks, Racheal. ---

Hi @mathieu.giard, could you delete your `.prismic` file in your home directory and try again? That file contains your authentication state, which appears to be corrupted for some reason. You can delete it with the following command: ```auto npx prismic-cli@latest logout ```
