    @RigoMiranda have you tried using the aws cli to examine your pinpoint endpoints and users? https://medium.com/@dantasfiles/testing-push-notifications-with-aws-amplify-9126bd621d3a

    so ive just figured out how to use aws-amplify's Auth.signIn() method to check a cognito pool. now i have to learn about vuex's state management. i can see that there are session token(s) persisting locally, but which one of the 7-9 items (in localStorage) do i save to and set from my Vuex state??.

    I am following the steps to use Amplify Datastore in iOS application from the link https://aws-amplify.github.io/docs/ios/datastore. But, the app is crashing saying "Fatal error: API category is not configured. Call Amplify.configure() before using any methods on the category.: file /Users/aftabahmed/Desktop/PROJECTS/Learning/iOS13/AWSAmplifyDataStoreApp/Pods/Amplify/Amplify/Categories/API/AmplifyAPICategory.swift, line 18". Can anyone help me solve this issue?

    Hi guys, does anyone know if there can be a workaround for this aws-amplify/aws-sdk-ios#2208

    We are using Cognito in production and is causing us bad reviews since after the refresh token is expired users experience a non working app and we have got no solution to handle it, has been already 16 days and not sure if a fix would come in or we need to move away from Cognito

    Hello guys, is there any way to add api with GET http method using amplify add api. Please help me

    Hey there. I'm going insane here trying to figure out something that seems to be quite easy. I've spent the last couple of days searching and trying stuff, but I still haven't managed to get this to work. It's related to using queryStringParameters in the API.get method - I need to return a set of elements from my table given a specific param. I simply cannot get the thing to work. I have an API.put method that's working, so both the API and the app are working correctly, but get just doesn't work - even if I send an API.get without params request, I still get a 404. I understand that this issue has been highly discussed, and supposedly a fix was implemented a while ago for this (since queryStringParameters wasn't a working functionality a while ago). Honestly, anything would be helpful as I'm going crazy trying to figure this out ahah

    Can you use amplify to build react native apps for iOS without access to xCode or a Mac,
    ?*
    Non-expo/ejected react native apps that is.

    I have a versioned @model using API.graphql(), how do I go about retrieving an older version of my document? Can I simply pass version into the input?
    The documentation doesn't say anything about this :(

    Ahghghg, I have a broken cloudformation template now, "CREATE_FAILED TriggerPermissions", and I can't update anything! Any recommendations on how to fix a broken backend config?
    Guilherme Campos
    @gpirescampos
    @aaronfay you can pull your backend configs from AWS - https://aws-amplify.github.io/docs/cli-toolchain/quickstart#amplify-pull. Not sure if that helps

    Hello, I am stuck with the below error when using aws-amplify in my react app. Auth.signIn is returning the confirmed user from cognito pool. I also receive the verification code via SMS. However, when I try to call Auth.sendCustomChallengeAnswer I am getting below error. Note that Auth.signIn and Auth.sendCustomChallengeAnswer are in two different methods. Please advise.

    code
    `
    handleSignIn = (a) => (param) => (e) => {
    if (this.validator.fieldValid('First Name')
    && this.validator.fieldValid('Last Name')
    && this.validator.fieldValid('Phone Number')) {

      let username = "+01" + this.state.phoneNumber.replace(/[^\d]/g, '');
      Auth.signIn({
          username, // Required, the username
      }).then(user => {
        console.log(user);
        this.setState({
          ['formActivePanel' + a]: param,
          ['formActivePanel' + a + 'Changed']: true,
          cognitoUser: user,
        });
      })
      .catch(err => {
        console.log(err);
        //TODO Handle ERROR
      });
    } else {
      this.validator.showMessageFor('First Name');
      this.validator.showMessageFor('Last Name');
      this.validator.showMessageFor('Phone Number');
    }

    }

    handleVerify = () => {
    if (this.validator.fieldValid('Verification code')) {
    let challengeResponse = "123456";//this.state.otpCode;
    let user = this.state.cognitoUser;
    console.log("otpCode:" + challengeResponse);
    console.log(this.state.cognitoUser);

      Auth.sendCustomChallengeAnswer({
        user,
        challengeResponse,
      }).then(user => {
        console.log(user);
      })
      .catch(err => {
        console.log(err);
        //TODO Handle ERROR
      });
    
    } else {
      this.validator.showMessageFor('Verification code');
    }

    }

    @GaurangBhatt in order to confirm the registration after receiving the code, I'm using Auth.confirmSignUp not Auth. sendCustomChallengeAnswer. I'm using email confirmation though, not sure if that changes anything
    Gaurang Bhatt
    @GaurangBhatt
    @gpirescampos thanks for quick response. I will try that.
    Guilherme Campos
    @gpirescampos
    This is the actual line await Auth.confirmSignUp(email, code, { forceAliasCreation: true })
    Gaurang Bhatt
    @GaurangBhatt
    Thanks. I am working on login so trying Auth.confirmSignIn

    Now I get below error.. the same thing just that instead of the challenge it is complaining about confirmation code. Console log clearly shows that it is receiving not-null confirmation code

    AuthError - Confirmation code cannot be empty console.<computed> @ index.js:1 ConsoleLogger._log @ ConsoleLogger.ts:91 ConsoleLogger.error @ ConsoleLogger.ts:142 AuthError @ Errors.ts:34 AuthClass.rejectAuthError @ Auth.ts:1976 AuthClass.confirmSignIn @ Auth.ts:889 Header.handleVerify @ Header.js:115

    Then I guess you must have some sort of parsing error somewhere, and the code isn't being sent correctly. Try, for example, inserting a string where the code goes, and see if you don't get the error anymore. If you stop getting that error, then it's parsing. IF not, then I don't really know
    Gaurang Bhatt
    @GaurangBhatt

    Got past that error... It was related to parsing and how I was sending parameters to sendCustomChallengeAnswer.
    Error
    Auth.sendCustomChallengeAnswer({ user, challengeResponse, })

    Fix -- I had to set otp to String(user inputed value) otherwise I get serialization error
    Auth.sendCustomChallengeAnswer(user, otp)

    hi
    is there any limit of how many relations can be returned when you request something with API.graphql(graphqlOperation))?
    so far I have 3 relations that must be returned when I a request a user, but I get only 2. User has many posts, each post has many comments and each comment has many reactions.
    for some reasons reactions are not returned
    the relation is set up correctly, all keys are present
    seems like it has something to do with the deepness of the relations returned

    I am trying to implement the amplify react HOC to use AWS cognito. I have followed the guides, but no matter what settings I use, after I authenticate, I am getting back an idtoken, refreshToken, and a accessToken. I only want to get back an access code. I have set my Amplify.configure to { oauth : {responseType: 'code'}} but that does not seem to be doing anything.

    @aaronfay when you put @versioned in a model, it adds a version field to the model and puts some extra logic in the createX, updateX, and deleteX resolvers. Otherwise, the version field is like any other field for queries.

    I'm confused about what to expect from amplify add hosting when I have 2 environments (dev & master). When adding hosting I have the option of DEV & PROD, where PROD would be using CloudFront and HTTPS. My expectation is that after merging my dev and master envs, that only 1 of these hosting options will be used (whichever is merged in), so how should I quickly test out my dev env, if ultimately it should be deployed with CloudFront and HTTPS?

    Did anyone run into this issue before? I created a PostConfirmation Lambda (add-user-to-group) using the amplify cli, pushed it, but when it gets invoked it fails with a not authorized error. Seems like the created IAM user has no rights to call getGroup or createGroup on Cognito. Anyone had this before? Or how to resolve this?

    Hi, I'm using Cognito to implement Single Sing On among a few web application (in different technologies, PHP, .NET, Java) and I'd like to provide custom login screen (app) for them - unfortunately customization of Cognito's build-in hosted UI is limited.
    I've found a lot of articles about customization of Amplify Auth UI itself, but I guess it's not what I'm looking for - To make SSO work I'd just need a single app to which other apps redirects (like hosted UI) which then authenticate user against user pool and redirects user back to the origin app. Unfortunately I cannot find any examples of such app, which is strange because I'd suppose that it's quite common requirement.

    Hi, I am using amplify and Appsync. I would like to manage createdAt and updatedAt fields on server side (in order to avoid false values from clients) and to use them in indexes. Is it possible to define fields in @model in a read only mode (and automatic updates)
    Daniel S. Dantas
    @dantasfiles
    @martinjuhasz Make sure your amplify\backend\auth\XXX\XXX-cloudformation-template.yml has the right permissions (cognito-idp:AdminAddUserToGroup, cognito-idp:GetGroup, cognito-idp:CreateGroup) in the # Updating lambda role with permissions to Cognito section of the file. If not, you might want to redo the auth setup.
