Call put put () inside a successful callback

Question

I am new to React and Redux.

I use response-redux to invoke the AWS Cognito service, which accepts an object containing a successful response and a failure. I get my JWT back from AWS Cognito when I console.log inside my success callback; however, as I can yield put()inside this callback, since it is not a generator ( function*) function .

Here is the code:

export function* getAWSToken(){
  // username, password and userPool come from react state
  // not showing code for brevity.

  const userData = {
      Username: username,
      Pool: userPool,
    };
  const authenticationData = {
    Username : username,
    Password : password,
  };

  const cognitoUser = new AWSCognito.CognitoIdentityServiceProvider.CognitoUser(userData);
  const authenticationDetails = new AWSCognito.CognitoIdentityServiceProvider.AuthenticationDetails(authenticationData);

  // This here is the callback
  cognitoUser.authenticateUser(authenticationDetails, {
    onSuccess(result){
      yield put(cognitoTokenObtained(result.getIdToken().getJwtToken())
    },
    onFailure(err){}
  });
}

( ), asyc, cognitoUser. authenticateUser , .

, yield, , , put.

export function* getAWSToken(){
  // username, password and userPool come from react state
  // not showing code for brevity.

  const userData = {
      Username: username,
      Pool: userPool,
    };
  const authenticationData = {
    Username : username,
    Password : password,
  };

  const cognitoUser = new AWSCognito.CognitoIdentityServiceProvider.CognitoUser(userData);
  const authenticationDetails = new AWSCognito.CognitoIdentityServiceProvider.AuthenticationDetails(authenticationData);

  // Note: since you're invoking an object method
  // you'll want to pass the object context (this) with the call via an array

  const token = yield apply(cognitoUser, cognitoUser.authenticateUser, [authenticationDetails, { onSuccess(response){return response}, onFailure(){} }]);

  yield put(cognitoTokenObtained(token.getIdToken().getJwtToken());
}
