Return type check problem of mutationWithClientMutationId after 0.7.0 update

[gtolarc]

After the 0.7.0 update, the following code has a problem.

const testMutation = mutationWithClientMutationId({
  name: 'TEST',
  inputFields: {
    name: { type: new GraphQLNonNull(GraphQLString) },
  },
  outputFields: {
    obj: {
      type, // some type
      resolve: (source, args, context, info) => source,
    },
  },
  mutateAndGetPayload: async (input, context, info) => {
    return new GraphQLError('TEST Error');
  },
}

Perhaps because the type defined in the output is forcibly checked, the error message return that was allowed in the past does not work. Is this the intended situation?

@gtolarc Thanks for reporting 👍
To confirm you get the error during type check and not in runtime, right?
Do you use Flow or Typescript?
Can you please paste the error message here?

I used typescript and this is an error that occurs at runtime.
