Unable to write scope information on jwt

Considering this:

1. Add Scope Information During Token Generation When generating the JWT, include the scope claim in the payload:

const jwt = require('jsonwebtoken');

const payload = {
  userId: '12345',
  scope: 'read:users write:users' // Add your scopes here
};

const secretKey = 'your-secret-key';
const token = jwt.sign(payload, secretKey, { expiresIn: '1h' });

console.log('Generated Token:', token);

2. Verify the Token and Scope When verifying the token, check the scope claim to ensure the required permissions are present:

const requiredScope = 'read:users';

jwt.verify(token, secretKey, (err, decoded) => {
  if (err) {
    console.error('Token verification failed:', err);
    return;
  }

  const tokenScopes = decoded.scope.split(' ');
  if (tokenScopes.includes(requiredScope)) {
    console.log('Scope verified successfully!');
  } else {
    console.error('Insufficient scope!');
  }
});

3. Use a Standardized Format If you're using OAuth 2.0 or OpenID Connect, the scope claim is often included as a space-separated string. Ensure your authorization server (e.g., Auth0, Keycloak) is configured to include the scope claim in the issued tokens.

4. Custom Claims If your token generation library or service doesn't support the scope claim natively, you can add it as a custom claim. Just make sure both the token issuer and consumer agree on the claim's format and usage.

5. Debugging Tips Use tools like jwt.io to inspect your tokens and verify that the scope claim is present.

Log the token payload during development to ensure the scope claim is being added correctly.

Hi,

To include scope information in your JWT token when using AWS Cognito, here's how to set it up:

1. Configure your Cognito App Client:

// Using AWS SDK
const cognito = new AWS.CognitoIdentityServiceProvider();

await cognito.updateUserPoolClient({
    UserPoolId: 'your-user-pool-id',
    ClientId: 'your-client-id',
    AllowedOAuthFlows: ['authorization_code'],
    AllowedOAuthScopes: ['openid', 'email', 'custom_scope'],
    ExplicitAuthFlows: ['ALLOW_USER_SRP_AUTH', 'ALLOW_REFRESH_TOKEN_AUTH'],
    GenerateSecret: true
}).promise();

2. Verify token in your Express middleware:

const jwt = require('jsonwebtoken');
const jwkToPem = require('jwk-to-pem');

const verifyToken = async (req, res, next) => {
    try {
        const token = req.headers.authorization.split(' ')[1];
        const decoded = jwt.verify(token, pem);
        
        // Check scopes
        const scopes = decoded.scope.split(' ');
        if (!scopes.includes('required_scope')) {
            return res.status(403).json({ error: 'Insufficient scope' });
        }
        
        next();
    } catch (error) {
        res.status(401).json({ error: 'Invalid token' });
    }
};

3. Request token with scopes:

const params = {
    ClientId: 'your-client-id',
    AuthFlow: 'USER_SRP_AUTH',
    AuthParameters: {
        USERNAME: username,
        PASSWORD: password,
        SCOPE: 'openid email custom_scope'
    }
};
