Apollo-Server | Apollo Server - | GraphQL library

I am trying to use import { applyMiddleware } from 'graphql-middleware'; library to add validation middleware on mutation's input.

So, I created a sample middleware function which is log input

I am trying to generate user id using uuid npm package for the id field in the user type. I am not sure where and how should I write it.

In my createUser mutation I am only asking the user to put in values for the name and email but not the id, as I wanted it to be generated by the uuid package, which is what I believe I have done it correctly in the createUser mutation.

Here is what I have in my schema.graphql file

I saw this statement in Graphql directive definition:

I've got a problem in my NestJs app. Project was running perfect until yesterday.

Apparently my node.js upgraded from 14.16.1 to 14.17.0. So I changed this version number in my engines object, in package.json. I executed yarn install again, to make sure everything was there, and tried yarn start:dev (which translates to nest start --watch).

I'm trying to make an _id field based off the title for topic object I've defined in my server. Here's the the schema.

I'm trying to write a NPM package with some React stuff included, at the moment it's just a component and a hook. To build the package I'm using Webpack. I've added react and react-dom to the externals section to ensure that it's not included in the bundle. I've also marked react as a peerDependency in the package.json and included it as a devDependency. Still I'm getting the error Invalid hook call when trying to use the bundle in another project. I think I've tried everything that I can Google my way to (like using the package with the purpose to solve this) with no luck.

My Webpack config looks like this at the moment:

It appears that GraphQL-queries with sort are broken on Neo4j Aura.

I'm using type-graphql in conjunction with typeorm, apollo-server-express and postgreSQL. I have a User and a Customer entity in a 1:n relationship, meaning one user can have multiple customers.

I can create users and customers just fine, but when attempting to retrieve the user associated to a customer using Apollo Server playground, I get an error message stating "Cannot return null for non-nullable field Customer.user."

When I check the database, the associated user id on the customer table is definitely not null (see attached image).
