Hi, I'm new to prismic from Japan,  
I'm creating a website using prismic and next.js(App router).

I changed a few things in prismic and published them, but the changes wouldn't appear on my website.  
I checked prismic api endpoint and I got error messages.

the error messages are;

- **{"message":"Missing Authentication Token"}** at **[https://customtypes.prismic.io](https://customtypes.prismic.io)** , **[https://your-repo-name.cdn.prismic.io/api/v2/graphql](https://your-repo-name.cdn.prismic.io/api/v2/graphql)** and **[https://if-api.prismic.io/if/write/your-repo-name--catalog-name](https://if-api.prismic.io/if/write/your-repo-name--catalog-name)**.
- **{"type":"api\_validation\_error","message":"Please specify ref"}** at **[https://your-repo-name.cdn.prismic.io/api/v2/documents/search](https://your-repo-name.cdn.prismic.io/api/v2/documents/search)**

I have no idea what to do. Could anyone help me?  
Thank you in advance.

**＜My website settings＞**

- Repository security ( API access ) is;  
Public API for Master only - Require an access token to preview future releases.
- Permanent access tokens is;  
published.

**＜My code settings＞**

.env.local

```auto
PRISMIC_ACCESS_TOKEN= *****************

```

prismic.js

```auto
export const createClient = ({ config }) => {
  const client = prismic.createClient(repositoryName, {
    routes,
    accessToken: process.env.PRISMIC_ACCESS_TOKEN,
    fetchOptions:
      process.env.NODE_ENV === 'production'
        ? { next: { tags: ['prismic'] }, cache: 'force-cache' }
        : { next: { revalidate: 5 } },
    ...config,
  });

  prismicNext.enableAutoPreviews({ client });

  return client;
};

```

I've already checked [this post](https://prismic.io/docs/api).

Hi Yusuke,

I have no problem access your repos and their data here:

I'm not sure why you're seeing GraphQL and IF messages here, are you using GraphQL?

Thank you for replying.  
I hadn't checked it. Now I started local server and did not get the error like you.  
I'm not sure the reason, but I'll keep creating the website.  
I appreciate your support.
