GET me/contacts returns 'Resource could not be discovered'

Question

I'm using this tutorial: Sign in users and call the Microsoft Graph API from a React single-page app (SPA) using auth code flow to my registered app on in Azure Active Directory

I want to get contacts from my Outlook Contacts so I added the Contacts.Read delegated permission.

After logging in (after I consent to the permission to read contacts) I can successfully issue a GET call to https://graph.microsoft.com/v1.0/me using the auth token.

When I use the same to token to call the https://graph.microsoft.com/v1.0/me/contacts endpoint, I get an HTTP 404 error:

{
    "error": {
        "code": "ResourceNotFound",
        "message": "Resource could not be discovered.",
        "innerError": {
            "date": "2023-03-23T14:50:53",
            "request-id": "d4e9c0cc-06f4-4c2a-9969-7889a968f5ba",
            "client-request-id": "d4e9c0cc-06f4-4c2a-9969-7889a968f5ba"
        }
    }
}

I can use Graph Explorer to retrieve my contacts, but when using my own token I get above error.

I'm not sure why this happen, am I miss something?

I agree with @Nam Nguyen, to resolve the error make use of @microsoft/microsoft-graph-client in the code.

Install and import the module by using below command:

npm install @microsoft/microsoft-graph-client
import @microsoft/microsoft-graph-client

Modify the code like below to fetch the contacts:

export async function getUser(authProvider: AuthCodeMSALBrowserAuthenticationProvider): Promise<User> { ensureClient(authProvider);  

const user: User = await graphClient!.api('/me')  
.select('displayName, mail, mailboxSettings, userPrincipalName')  
.get();  
return user;  

var response: PageCollection = await graphclient!  
.api('/me/contacts')  
.get();

For more in detail, refer the GitHub Blog by jasonjoh : GitHub - This sample demonstrates how to use the Microsoft Graph JavaScript SDK to access data.

I tried to reproduce the same in my environment in Postman and got the results like below:

I created an Azure AD SPA Application and granted API permissions:

Now, I generated access token using PKCE flow like below:

https://login.microsoftonline.com/TenantID/oauth2/v2.0/token

client_id:ClientID
scope:https://graph.microsoft.com/.default
grant_type:authorization_code
code:code
code_verifier:S256
redirect_uri:https://jwt.ms

By using the above generated access token, I am able fetch the contacts like below:

https://graph.microsoft.com/v1.0/me/contacts
