Environment information

``` # Put output below this line System: OS: Linux 5.17 Arch Linux CPU: (16) x64 AMD Ryzen 7 3700X 8-Core Processor Memory: 3.81 GB / 31.26 GB Container: Yes Shell: 5.8.1 - /bin/zsh Binaries: Node: 16.13.2 - ~/.nvm/versions/node/v16.13.2/bin/node Yarn: 1.22.17 - /usr/bin/yarn npm: 8.1.2 - ~/.nvm/versions/node/v16.13.2/bin/npm Browsers: Firefox: 97.0 npmGlobalPackages: @aws-amplify/cli: 7.6.15 corepack: 0.10.0 npm: 8.1.2 ```

Describe the bug

Attempting to require("aws-appsync") causes this error to return:

Lambda:Unhandled", message: "Cannot convert undefined or null to object"

I'm following the guide and using the example code from here: https://aws.amazon.com/blogs/mobile/supporting-backend-and-internal-processes-with-aws-appsync-multiple-authorization-types/

If I do the same import locally in a node shell, using the same version of aws-appsync the import works fine in node 14 and node 16.

amplify mock function also fails with the same error

Expected behavior

The Lambda function should run without error.

Reproduction steps

run amplify add function
go through the configuration steps, in my case I gave access to api and auth as this is a new user registration lambda
cd amplify/backend/function/plateletAdminAddNewUser/src
yarn add isomorphic-fetch aws-appsync uuid graphql-tag graphql
amplify push

require("isomorphic-fetch");
const AUTH_TYPE = require('aws-appsync').AUTH_TYPE;
const AWSAppSyncClient = require('aws-appsync').default;

        //  },
        body: JSON.stringify("hello"),
    };
    return response;
};

In my GraphQL schema:

type Mutation {
   registerUser(name: String, email: String, tenantId: ID, roles: [Role]): String @function(name: "plateletAdminAddNewUser-${env}")
 }

In my React app:

                await API.graphql(
                    graphqlOperation(mutations.registerUser, {
                        name: state.name,
                        email: state.email,
                        roles: rolesState,
                        tenantId,
                    })
                );

I was able to work around the issue for now by downgrading:

yarn add aws-appsync@4.0.0

djsjr commented 2 years ago

npm install aws-appsync@4.0.0 did not solve it for me. Same error

menendezjaume commented 2 years ago

Same issue here. Downgrading to 4.0.0 fixed it for me too.

ffxsam commented 2 years ago

Downgrading to 4.0.0 worked for me too. Thanks!

@chrisbonifacio Any idea what's going on here?

chrisbonifacio commented 2 years ago

Downgrading to 4.0.0 worked for me too. Thanks!

@chrisbonifacio Any idea what's going on here?

Hey @ffxsam, we've since updated our AppSync docs to recommend using node-fetch when performing GraphQL mutation from a Lambda and/or Node.js rather than the AppSync SDK. Apologies for the confusion.

https://docs.amplify.aws/lib/graphqlapi/graphql-from-nodejs/q/platform/js/

ffxsam commented 2 years ago

@chrisbonifacio Perfect, thanks for the heads-up on that!

dsharygin commented 2 years ago

@chrisbonifacio Thank you for the update. Can you please elaborate what this means for the AWSAppSync JS SDK? We are using AWSAppSyncClient caching capabilities in a few places in our code.

ffxsam commented 2 years ago

@chrisbonifacio Just in retrospect: since this was a breaking change, shouldn't the version have been bumped to 5.0.0?
