Describe the bug

While running runWithAmplifyServerContext on the server side, it doesn't provide me with the current user session, even when the user is logged in. However, the code works fine when deployed but the issue occurs on my localhost.

async function getSession() {
  try {
    const currentUserSession = await runWithAmplifyServerContext({
      nextServerContext: { cookies },
      operation: async (contextSpec) => {
        return (await fetchAuthSession(contextSpec)).tokens
      }
    });
    console.log(currentUserSession)
    return currentUserSession;
  } catch (error) {
    logger.error(error, "Session Fetch Error on Server Component");
    return {};
  }
}

Expected behavior

It should give user access token and id token

{
  accessToken: {
    toString: [Function: toString],
    payload: {
      sub: xxxx,
      iss: xxxx,
      client_id: xxxx,
      origin_jti: xxxx,
      event_id: xxxx,
      token_use: 'access',
      scope: xxxx,
      auth_time: xxxx,
      exp: xxxx,
      iat: xxxx,
      jti: xxxx,
      username: xxxx
    }
  },
  idToken: {
    toString: [Function: toString],
    payload: {
      sub: xxxx,
      email_verified: true,
      iss: xxxx,
      'cognito:username': xxxx
      origin_jti: xxxx,
      aud: xxxx,
      event_id: xxxx,
      token_use: 'id',
      auth_time: xxxx
      exp: xxxx,
      iat: xxxx,
      jti: xxxx,
      email: xxxx
    }
  },
  signInDetails: { loginId: xxxx, authFlowType: xxxx }
}

Hi @prabhat-sunai thank you for opening this issue.

Since you can only reproduce this issue locally, could you do the following for further investigation?

• Open the developer tool, and inspect whether the cookie store contain the auth tokens after signing in an end user
• If the auth tokens present in the cookie store, could you inspect the network requests that were sending to your local Next.js dev server contains a cookie header that includes the auth tokens you saw in the cookie store?

Also are you using Safari for testing locally?

[prabhat-sunai]

The cookie store contains auth tokens after signing in and it is also present in network requests that were sent to local Next JS server. Also, the client side query is fine and access token is being shown in client side query. I also checked the cookie object from next/header and all the tokens are shown there. I am using Google Chrome for testing locally

[HuiSF]

Thanks for providing more information @prabhat-sunai I have no clue what's happening here reading your description if the cookies presents in all the locations.

When you are saying:

it doesn't provide me with the current user session, even when the user is logged in

Did fetchAuthSession() call throw, or it returned undefined for .tokens? If you log the ensure result returned by the API call, what did it look like?

Also, is it possible to create a minimal reproducing app so I can also help inspect?
