Queries fails with missingValue error all time after Apollo migration to 1.x version

Question

I am trying to update the Apollo dependency for one of my projects from 0.53.0 to 1.x and I have some issues with it. For schema management and code generation I have used apollo-ios-cli.

After updating my classes to fix some errors generated by different type names or missing ApolloAPI import the project is building & running again, but each time when I'm calling any query it ends up with the following error:

GraphQLExecutionError(path: __typename, underlying: ApolloAPI.JSONDecodingError.missingValue)

After I've looked into it a bit deeper, I've found that backend is returning data as needed but the app throws an error in the JSONResponseParsingInterceptor, on the parseResult method. No matter what type of cachePolicy I'm using, it always throws an error from both parseResult and parseResultFast` methods.

Query example:

query GetAppConfigs {
  result: app_config {
        key
    value
    type
  }
}

Any idea?

Seeing the same issue after updating from 1.0.5 to 1.1.2 (ApolloAPI.JSONDecodingError.missingValue) for all queries.

Had same issue here, downgrading to 1.0.5 resolved the issue.

Hi, good day. Tried it in 1.3, in what version is it fix. Thanks!

[BobaFetters]

@psdevss This was fixed in the 1.1.3 release

Ahh quick question, why in my query and generating. typename is always there for every object. Actually trying it in our mockserver and json response works if typename is added on each object

@psdevss not 100% clear what you are asking, this issue and #2955 were caused by __typename being added to root field types when using custom names for the root fields (Query, Mutation, Subscription), other types should have __typename generated for them. If you are experiencing an issue I would recommend opening a new issue and providing detailed information on how to reproduce the issue like in #2955
