Aws-mobile-appsync-sdk-js: AWS-AppSync SDK contains AWS-SDK dependency

[indunilasanka]

AWS-AppSync SDK (javascript: version 3.0.2) contains AWS-SDK dependency ( "aws-sdk": "2.518.0"). Are there any simplified versions. This full sdk is a bit of a heavy for our applications

@elorzafe is there any plan to update to aws-sdk version 3 which is tree shakeable?

Thanks for the feedback, I will talk to other team members to see how can we improve this.

@elorzafe can you provide an update?

Hey, I've started upgrading to aws-sdk v3 and aws-crypto. Please have a look here: https://github.com/awslabs/aws-mobile-appsync-sdk-js/compare/master...CasperAlant:upgrade-aws-sdk
However, I'm really struggling to make any meaningful progress with the tests.

I tried reimplementing the tests using nock in aws-appsync/tests/link/complex-object-link.test.ts

test('Is run for mutations with a S3Object', done => {
    const scope = nock('https://bucket.s3.region.amazonaws.com')
    .put('/')
    .reply(200)

    const link = complexObjectLink(null);

    const operation = {
        query: gql`mutation { someMutation { aField } }`,
        variables: {
            aFile: {
                bucket: 'bucket',
                key: 'key',
                region: 'region',
                mimeType: 'mimeType',
                localUri: {},
            }
        },
    };

    execute(prepareLinkForTest(link), operation).subscribe({
        next: () => {
          console.log("f")
            expect(scope.isDone()).toBeTruthy();
          console.log("g")
            done();
          console.log("h")
        },
        error: fail
    });
});

but every test that expects a request to be made fails with:

TypeError [ERR_INVALID_ARG_TYPE]: The first argument must be one of type string, Buffer, ArrayBuffer, Array, or Array-like Object. Received type object
    at Function.from (buffer.js:232:9)

    at runCallback (timers.js:705:18)

Any guidance would be appreciated.
