Automatic Upload to S3 Fails

[andrewjzhou]

Hi I am reopening an issue discussed previously (#25). I followed the updated instructions (https://awslabs.github.io/aws-mobile-appsync-sdk-ios/#complex-objects) to a tee and still experienced no success with automatically uploading to S3. I can see that there is an S3Object in my dynamoDB table but nothing gets uploaded to my S3 bucket. I tried uploading the same file using TransferUtility and it works, so I'm not sure what the issue is.

Have you tried making the S3Object a top level item? I know according to the docs it's not required to be, but I've had success doing it with something like this:
create(post: Post, imageToUpload: S3ObjectInput)

As I know, the br3nt0n is right, S3Object has to be in top level item.

For example if you have:
create(post: PostInput)

and PostInput is

type PostInput {
  	id: ID!
  	author: String!
  	title: String
  	file: S3Object
  }

change mutation to:
create(post: PostInput, file: S3ObjectInput)

and PostInput to:

type PostInput {
  	id: ID!
  	author: String!
  	title: String
  }

Reason:
In AppSyncComplexObjectsInterceptor, when deciding if operation should upload S3Object, this condition has to be met:
request.operation.queryDocument().contains("S3ObjectInput")

You can check manually for string "S3ObjectInput" in generated Apollo source file for mutation.
If String object OPERATION_DEFINITION in said mutation source doesn't contain string "S3ObjectInput", interceptor will simply ignore it and will not upload file.
