Error: The GraphQL schema is not provided (Express)

Expected Behaviour

I followed the recipe from https://github.com/graphql/graphql-http#recipes for migration from express-graphql. When I run the server I would expect it to work as with express-graphql (no errors).

Actual Behaviour

When starting the server I get:

0|www    | Internal error occurred during request handling. Please check your implementation. Error: The GraphQL schema is not provided
0|www    |     at handler (/Users/e/Desktop/projects/my/node_modules/graphql-http/lib/handler.js:202:23)
0|www    |     at processTicksAndRejections (node:internal/process/task_queues:96:5)
0|www    |     at async requestListener (/Users/e/Desktop/projects/my/node_modules/graphql-http/lib/use/express.js:28:34)

Debug Information
Help us debug the bug?

Further Information

Using:

• graphql-http 1.7.0
• @graphql-tools/schema 9.0.4 to create my schema (is this not supported?)

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

@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.
