Error: The GraphQL schema is not provided (Express) about graphql-http HOT 6 CLOSED

@enisdenjo noticed that I was using a callback with express-graphql and it had been working. However, that way it doesn't work with graphql-http since it's not a valid argument as it seems to expect an object.

graphqlHTTP((req) => ({
    schema
}));

graphqlHTTP({
    schema
});

At least now I know what's the problem and it's on my end.

@chongma, not sure, I just ended up migrating to Yoga GrahpQL which wasn't too bad: https://the-guild.dev/graphql/yoga-server/docs/migration/migration-from-express-graphql

from graphql-http.

i guess it is using the formatError function now https://github.com/graphql/graphql-http/blob/main/docs/modules/handler.md#formaterror

Hey thanks for reporting. Can you please share your server implementation code? Are you sure you're providing a schema?

I am also migrating from express-graphql but I have been using the callback. How do I keep it?

from graphql-http.

It seems to work like this

router.use(path,
        middleware,
        (req, res) => {
            // ... do something
            const handler = createHandler({
                schema,
                context: {
                    loaders: createLoaders(),
                    user,
                    ipaddress: req.ip
                },
                customFormatErrorFn: function (err) {
                    // this should catch any unhandled errors from the resolvers
                    console.error(err)
                }
            })
            handler(req, res)
        })

The trouble I am having now is whether customFormatErrorFn will work as expected
