AWS-Amplify API is always returning 403 unauthorized with angular

AWS-Amplify using API.get() with angular to call Serverless API with IAM authentication is always returning 403 unauthorized, even though that I have followed all the instructions posted on GitHub and stackoverfolw,

here is my code for using api.get:

` async testApiCall() { const user = await Auth.currentAuthenticatedUser(); const token = user.signInUserSession.idToken.jwtToken;

const request = {
    headers: {
        Authorization: token
    }
};

var response = await API.post('orders', '/orders', request)
    .catch(error => {
        alert('error' + error);
    });
    alert(response);
document.getElementById('output-container').innerHTML = JSON.stringify(response);

}`

and here is my config.ts:

export default { MAX_ATTACHMENT_SIZE: 5000000, s3: { REGION: "eu-central-1", BUCKET: "xxxxxx" }, apiGateway: { REGION: "eu-central-1", URL: "xxxxxxxx" }, cognito: { REGION: "eu-central-1", USER_POOL_ID: "xxxxxxxxxxxxxxxxx", APP_CLIENT_ID: "xxxxxxxxxxxxxxxxx", IDENTITY_POOL_ID: "xxxxxxxxxxxxxxxxx" } };

And here is what I have in environment.ts:

export const environment = { production: true, amplify: { Auth: { identityPoolId: 'xxxxxxxxxxx', region: 'eu-central-1', userPoolId: 'xxxxxxxxx', userPoolWebClientId: 'xxxxxxxxxxx' }, API: { endpoints: [ { name: "orders", endpoint: "xxxxxxxxx" } ] } } }; any suggestions please?

@khaledshamat if you are using IAM authentication, and as I could assume based on your config, you are using the Cognito Federated Identity Pool service right? In that case, you shouldn’t do the following:

const request = {
    headers: {
        Authorization: token
    }
};

The amplify library will fetch the credentials internally and sign the request. Can you also open the debug mode by putting window.LOG_LEVEL='DEBUG' to get more info?
