How to suppress "Resolve function for "xyz" returned undefined"

[tomitrescak]

Is it possible? I don't care if that field is undefined.

Documentation says that I can enforce this behaviour with "forbidUndefinedInResolve", but I want opposite of that.

http://docs.apollostack.com/apollo-server/errors.html

I even set { allowUndefinedInResolve: true } in graphql options and no luck.

[EDIT] I see that these options are for the server 1.x. So how to suppress this in 2.x ?

For 0.2.0 you have to pass the option to makeExecutableSchema, which is a function from graphql-tools.

Thanks for your answer!

Is there any documentation to graphql-tools? The documentation from Github points to old version of Apollo Server.

Right here: http://docs.apollostack.com/graphql-tools/generate-schema.html

Here is what I got so far... https://github.com/payner35/reduxToast

But I'm still getting undefined errors

const executableSchema = makeExecutableSchema({
    typeDefs: Schema,
    resolvers: Resolvers,
    //connectors: Connectors,
});


createApolloServer({
    graphiql: true,
    pretty: true,
    schema: executableSchema,
    printErrors: true, // optional
    allowUndefinedInResolve: true // optional
});

@payner35 I'm pretty sure you have to pass that option to makeExecutableSchema, not into createApolloServer (which I assume is from meteor-integration).

Thanks @helfer .. working now

const executableSchema = makeExecutableSchema({
    typeDefs: Schema,
    resolvers: Resolvers,
    //connectors: Connectors,
    printErrors: true, // optional
    allowUndefinedInResolve: true // optional
});


createApolloServer({
    graphiql: true,
    pretty: true,
    schema: executableSchema
});

@helfer I think the documentation is out of date. It still says forbidUndefinedInResolve is a function and you should use it to update your schema like so:

import { forbidUndefinedInResolve } from 'graphql-tools';

forbidUndefinedInResolve(schema); // TypeError: forbidUndefinedInResolve is not a function

Regardless, I can't get any errors to show. I'm trying

module.exports = makeExecutableSchema({
    typeDefs: schema,
    resolvers: require('./resolvers'),
    allowUndefinedInResolve: false,
    printErrors: true,
    logger: {
        log: err => {
            console.log(err);
        }
    },
});

And when I run I query I get back:

{"errors":[{"message":"Unknown operation named \"undefined\"."}]}

But no error is logged either to my terminal nor GraphiQL so I don't know what the issue is.

Edit: Nvm, that particular error appears to be a bug in GraphiQL, so Apollo never saw it. My logger is being hit now for other errors, although it's showing up twice now. Oh well.
