Environment information

Hi I am also facing configuration issue while migrating from AWS Amplify v5 to v6.

Amplify configuration is as follows:

import { Amplify } from 'aws-amplify';
Amplify.configure({
  Auth: {
    Cognito: {
      userPoolId: process.env.REACT_APP_COGNITO_USER_POOL_ID || '',
      userPoolClientId: process.env.REACT_APP_COGNITO_APP_CLIENT_ID || '',
    },
  },
});

However, I am receiving the error: AuthUserPoolException: Auth UserPool not configured.

aws amplify signIn code:

  try {
        const { nextStep } = await signIn({
          username: email,
          password: password,
          options: {
            country_code: modalDetails?.data?.country_code,
          },
        });

        if (nextStep?.signInStep === 'CONFIRM_SIGN_IN_WITH_NEW_PASSWORD_REQUIRED') {
          setIsNewPasswordRequired(true);
          setIsButtonLoading(false);
          return;
        }
        updateLocalesToDB(); 
      } catch (ex) {
        throw new Error(
          getErrorMessageByCognito((ex as Error)?.message, [CognitoPrefix.PreAuthentication])
        );
      }

I tried printing configuration, the configuration are getting called.

it returns following object:

{
    "Auth": {
        "Cognito": {
            "userPoolId": "app-userPoolId",
            "userPoolClientId": "app-userPoolClientId"
        }
    },
    "API": {
        "REST": {
            "YourAPIName": {
                "endpoint": "app-endpoint",
                "region": "app-region"
            }
        }
    }
}

Describe the bug

At the time of login getting following error.

aws-amplify SignIn call gave error - AuthUserPoolException: Auth UserPool not configured.

Expected behavior

It should successfully do the login.

Reproduction steps

install: "aws-amplify": "^6.6.7",

Code Snippet:

  try {
        const { nextStep } = await signIn({
          username: email,
          password: password,
          options: {
            country_code: modalDetails?.data?.country_code,
          },
        });

        if (nextStep?.signInStep === 'CONFIRM_SIGN_IN_WITH_NEW_PASSWORD_REQUIRED') {
          setIsNewPasswordRequired(true);
          setIsButtonLoading(false);
          return;
        }
        updateLocalesToDB(); / / This request should happen asynchronously, so not putting await
      } catch (ex) {
        throw new Error(
          getErrorMessageByCognito((ex as Error)?.message, [CognitoPrefix.PreAuthentication])
        );
      }

Hi @Sneha-Syngenta thanks for raising the issue,
Could you please try double check the following

• Amplify.configure is called at the root of your app (example index.js) so this gets configured first and then the signIn api gets called.
• can you call Amplify.getConfig() right before calling signIn to check if the required configuration is present
• Is it possible Amplify.configure might be called twice and one of the times userPoolId: process.env.REACT_APP_COGNITO_USER_POOL_ID || '' might result in an empty string

[Sneha-Syngenta]

Thank you for your response.

I did verified this already, config are getting called with proper values whatever we have defined in amplify.config.

it returns following object:

{
    "Auth": {
        "Cognito": {
            "userPoolId": "app-userPoolId",
            "userPoolClientId": "app-userPoolClientId"
        }
    },
    "API": {
        "REST": {
            "YourAPIName": {
                "endpoint": "app-endpoint",
                "region": "app-region"
            }
        }
    }
}

But somehow it is giving above error.

Did you get a chance to validate what did Amplify.getConfig() return right before calling signIn() API?

@Sneha-Syngenta, wanted to ping you again to see if you're still blocked here or if you had a chance to validate what Amplify.getConfig() returns right before calling signIn(). Thanks!

Hi,

Thanks for your reply. I already shared in the previous msg that we did verified this

config are getting called with proper values whatever we have defined in amplify.config.

it returns following object:

{
    "Auth": {
        "Cognito": {
            "userPoolId": "app-userPoolId",
            "userPoolClientId": "app-userPoolClientId"
        }
    },
    "API": {
        "REST": {
            "YourAPIName": {
                "endpoint": "app-endpoint",
                "region": "app-region"
            }
        }
    }
}

But somehow it is giving above error.

@Sneha-Syngenta, can you share your package.json file so we can see what dependencies you have? And with this being a migration from v5 to v6, can you also do the following:

• delete your package-lock.json file
• delete your node_modules folder
• reinstall dependencies with npm install

Hey @cwomack , I'm experiencing the same issue. I made sure to print out the config before my cognito-related function ran (sign in/out, etc.), and it indeed is printing out correctly. I also followed the instructions you gave above, but when my code calls the signIn API, I get the same error: "Auth user pool not configured."

I should also add that, for my team, we utilize Amplify for two of our microservices, and just last week both were working fine with no changes being made to the config, but now both services error out with "Auth user pool not configured."

[Sneha-Syngenta]

@cwomack i did followed same step you mentioned in thread but somehow no luck.

issue still persist with same error "Auth UserPool not configured."

UPDATE: To anyone wondering, I figured out what was wrong with my implementation. The signIn API call was put into a function that was marked to "use server" (I'm using nextjs 14), which was being used within a server action, but the issue with this is that the config appears as an empty object, and that likely because the Amplify config is on the client side:

"use client";

import {Amplify, type ResourcesConfig} from "aws-amplify";

export const authConfig: ResourcesConfig["Auth"] = {
    Cognito: {
        userPoolId: String(process.env.NEXT_PUBLIC_USER_POOL_ID),
        userPoolClientId: String(process.env.NEXT_PUBLIC_USER_POOL_CLIENT_ID),
    },
};

Amplify.configure(
    {
        Auth: authConfig,
    },
    {
       ssr: true // use cookies for state storage over the default, local storage
    }
);

export default function ConfigureAmplifyClientSide(){
    return null;
}

Where as my signIn API call happens on the server (this executes first), and so, the fix is to remove the "use server" statement from the function call (or from the top of your file; if your Cognito actions are all in one file). Hope that helps. If my understanding of the way Amplify works with respect to client/server is wrong, please correct me, thanks!

There might be multiple versions of aws-amplify installed in node_modules. Can you try running npx npm-why aws-amplify in the app root folder ? This should give you a list of all the installed versions.
