Describe the bug

After upgrading from @aws-amplify/cli@12.0.0 to @aws-amplify/cli@12.10.1 I am unable to do any mutations. All of them return the error: "The variables input contains a field that is not defined for input object type 'DirListInput' "

Expected behavior

Carry out the mutation successfully without throwing an error as it did in @aws-amplify/cli@12.0.0

Reproduction steps

I am running a react app with "aws-amplify": "5.3.17"

1. (simplified) schema.graphql:

type DbDirTable @model(timestamps: { createdAt: "createdAt", updatedAt: "modifiedAt" }) {
  id: ID!
  createdAt: AWSDateTime!
  modifiedAt: AWSDateTime!
  dirList: [DirList!]!
  copiedFromId: String
}

type DirList {
  id: ID!
  items: [DirListItem!]!
  title: String
  colour: String
}

type DirListItem {
  id: ID!
  note: String
  visited: Boolean
}

2. After running amplify push --y it changed:

src/API.ts
src/graphql/mutations.ts
src/graphql/queries.ts
src/graphql/schema.json
src/graphql/subscriptions.ts

The difference in those files was that it added __typename to every type, input, mutation and query

3. Then I call

await API.graphql<GraphQLQuery<UpdateDbDirTableMutation>>(graphqlOperation(updateDbDirTable, { input: inputData }));

where inputData is:

{
  {
    "id": "3894a81b-4e93-4627-aae1-0a0617a8ed75",
    "dirList": [
        {
            "id": "a9cb6ec9-0254-4d37-ac96-e25e46f50a42",
            "items": [],
            "title": "One",
            "colour": null,
        },
        {
            "id": "09701984-fe07-4140-b36a-c9ecd8ca0549",
            "items": [
                {
                    "id": "6535fb67-f55d-475c-b32d-065f5b26f4ee",
                    "note": null,
                    "visited": null,
                }
            ],
            "title": "Two",
            "colour": null,
        }
    ]
}

But it throws the error

[
    {
        "path": null,
        "locations": null,
        "message": "The variables input contains a field that is not defined for input object type 'DirListInput' "
    }
]

4. updateDbDirTable is auto-generated in src/graphql/mutations. I am not using any custom resolvers or overrides

Additional information

If I discard changes in the graphql the code in step 3 works ok

If I downgrade to 12.0.0 and re-generate the graphql files the code in step 3 works ok

Same issue on 12.4.0 because it adds the same changes as 12.10.1 to the auto-generated graphql and API

I noticed that if I keep all of the regenerated changes and only discard the src/graphql/queries.ts then the code works ok

The only new change in src/graphql/queries.ts is that it added __typename everywhere.

This is strange since all my queries, when called directly, work fine with the newly generated file and they fetch the data ok.

Before submitting, please confirm:

• I have done my best to include a minimal, self-contained set of instructions for consistently reproducing the issue.
• I have removed any sensitive information from my code snippets and submission.

Hey @ok-martin 👋 thanks for raising this! I'm going to transfer this over to our API repo for tracking 🙂

Hi @ok-martin, the changeset from 12.0.0 to 12.10.1 includes this codegen change which might have caused this. I've tried to reproduce this and noticed the typeName additions as well. However I have some questions:

I noticed that if I keep all of the regenerated changes and only discard the src/graphql/queries.ts then the code works ok

I am confused by this part since the types defined here are independent of the mutation that is failing for you. Do you happen to have a diff of mutations.ts that is generated? I see that in my repro, there is an additional diff other than the __typeName as seen below:

[ok-martin]

Hi @phani-srikar I am confused by that too.

Here is the diff on the mutation file:

It is essentially the same but with __typename added

[dpilch]

As a workaround, you can disable the addition of __typename in the query. In your .graphqlconfig.yml file set typenameIntrospection to false.

projects:
  typename:
    extensions:
      amplify:
        typenameIntrospection: false

Another thing to try, could you add a newline somewhere in GraphQL schema and then try to amplify push. This will force the API resource to update.

I am still experiencing the issue.

It seems that it only fails to update on objects that are already in the database. If I insert a new row and then try to update it, then it all works ok.

However, when I try to update a row that was already there (from version 12.0.0) then the update fails.

[ok-martin]

I can confirm that the problem occurs when updating sub-fields that are missing __typename.

Is there a way to auto populate those sub-fields with __typename?

P.S thank you @dpilch. Your workaround works but I would rather solve it the proper way in case this becomes an issue with the future versions of Amplify :)
