Describe the bug

Hi i'm using AWS Amplify with DataStore to create fullstack app and i faced a problem that doesn't go away.

I will describe my problem with a basic example.

Schema:

type Post @model {
  id: ID!
  owner: String
  title: String
  content: String!
}

If i try to save a data to the Post model in NextJS API route it will work but if i add

@auth(
    rules: [
      { allow: owner, ownerField: "owner" }
      { allow: public, operations: [read] }
    ]
  )

rule like that and try to save a data, the data will create only locally and not properly.

Here is my API route code example:

import Amplify, { AuthModeStrategyType, withSSRContext } from "aws-amplify";
import { NextApiRequest, NextApiResponse } from "next";
import { Post } from "../../../models";
import config from "../../../aws-exports";

// Amplify SSR configuration needs to be done within each API route
Amplify.configure({
  ...config,
  DataStore: {
    authModeStrategyType: AuthModeStrategyType.MULTI_AUTH,
  },
  ssr: true,
});

export default async (req: NextApiRequest, res: NextApiResponse) => {
    const { Auth, DataStore } = withSSRContext({ req });
  
    try {
      const user = await Auth.currentAuthenticatedUser();
  
      if (!user) {
        return res.status(401).json({ error: "Unauthorized request!" });
      }

      const newPost = await DataStore.save(new Post({
          title: "test",
          content: "Lorem ipsum dolor"
      }));

      return res.status(200).json(newPost);
    } catch (error) {
      console.log(error);
      return res.status(400).json(error);
    }
  };
  

Expected behavior

The data should be created on cloud like when i adding data without @auth rule.

Reproduction steps

Try to create data on NextJS API route you probably will facing with the same problem.

Hey @casperibo, I would enable logs with Amplify.Logger.LOG_LEVEL = 'DEBUG' and then check the logs in your Next.js app to see there are any warnings or errors coming from DataStore. If there are, please share them here.

[casperibo]

Hi @iartemiev thank you for your response, i finally could see an error.

I think DataStore try to use API key when i try to save data.

Normally i would do AUTH_TYPE.AMAZON_COGNITO_USER_POOLS, on API but do i have to declare anything on my DataStore.save command?

I faced some error when try to debug.

[DEBUG] 20:34.280 DataStore - Mutation failed with authMode: API_KEY
[DEBUG] 20:34.514 AuthClass - getting current authenticated user
[DEBUG] 20:34.514 AuthClass - get current authenticated userpool user
[DEBUG] 20:34.514 AuthClass - Failed to get user from user pool
[DEBUG] 20:34.515 AuthClass - The user is not authenticated by the error No current user
[DEBUG] 20:34.516 DataStore - Attempting sync with authMode: API_KEY

If you can look my code again, I'm getting user from withSSRContext and i can console.log current user successfully.

[casperibo]

I console log Auth and Datastore coming from withSSRContext({ req }) and found;

Auth._config.aws_appsync_authenticationType is "API_KEY";
DataStore.amplifyConfig.aws_appsync_authenticationType is "API_KEY";

I try to change them but still getting same "Mutation failed with authMode: API_KEY" error.

// Didn't work
Auth._config.aws_appsync_authenticationType = "COGNITO_USER_POOLS";
DataStore.amplifyConfig.aws_appsync_authenticationType = "COGNITO_USER_POOLS";

Hi @iartemiev can you take a look this situation when you available? I'm still in same situation.

[casperibo]

@chrisbonifacio Hi, i saw your message in a aws-amplify issue page(link below), the problem still didn't fixed.

Should i use API in NextJS API routes or is there a way to use  DataStore for authenticated requests?

This will be fixed in #10088
