Error occurs in buildMutation function when calling a Mutation

Note: If your issue/feature-request/question is regarding the AWS AppSync service, please log it in the
official AWS AppSync forum

Do you want to request a feature or report a bug?
Report a possible bug.

What is the current behavior?
Calling a graphlQL mutation causes an error in aws-appsync/helpers/offline in buildMutation. The error is caused by the variablesInfo param not having the required attribute inputType. I have added a screenshot of the debugger paused at the line where the error occurs. The Watch window pane shows the values of isVariablesInfo and variablesInfo.

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem.
I have created 2 different AppSync projects that both have this same problem for react-native by first doing:

1. react-native init <proj-name>
2. cd proj-name and then amplify init
3. amplify add api
4. Edit schema
5. amplify push
6. Following the documentation for setting up the AWS AppSync Client and using offline-helpers. Here is a link to the React-Native example I have done.

What is the expected behavior?
Using a GraphQL mutation doesn't error out due to the missing field.

Which versions and which environment (browser, react-native, nodejs) / OS are affected by this issue? Did this work in previous versions?

Package Dependencies:
"dependencies": {
"aws-amplify": "^1.1.19",

@ChrisFieldsII Can you paste your schema, and mutation your are trying to do? Thanks!

[ChrisFieldsII]

Hello @elorzafe . Thanks for the reply.

Schema:
schema.txt

The first 2 images are the Mutations I am trying to run. The updateScope mutation works just fine and I do not get the error. The createPhoto mutation is the one that errors out due to inputType not being present.
The third image is the container that just passes the Mutation functions into its View component.
The fourth image is the View component Camera calling the mutation functions with the variables

Hello,

Has there been any luck recreating the error or anyone else that has experienced it?

I am still running into the same error when calling mutations via the graphqlMutation helper. variablesInfo just contains the variables object passed in when calling the mutation function in my client code causing the error.

I am currently commenting out the code and setting inputTypeVersionField to false

@elorzafe @ChrisFieldsII I'm having the same issue on isVariablesInfo and variablesInfo. Did you find a solution?
