I had an error with PrismaClientKnownRequestError - would not compiled:

This is the suggested solution:

import { Prisma } from '@prisma/client';

For catching the error:

if (error instanceof Prisma.PrismaClientKnownRequestError )
  
}

Hey @tbecker, this is related to you using a never version of Prisma than the one we used for writing this tutorial. However, I just updated the tutorial to the latest prisma version. So now everything should be fine. We will also use exact versions when installing the dependencies to avoid confusion. Thank you for pointing this out!

For me, app crashes with Promise rejection.

return Promise.reject(
  new GraphQLError(`Cannot post comment on non-existing link with id '${args.linkId}'.`)
)

Now, returning just the error, gives me the result I need

return new GraphQLError(`Cannot post comment on non-existing link with id '${args.linkId}'.`)

Making a note to return the error instead of making promise rejections in my code. This might be related to a new API change, hope you can take a look at this matter and if needed update the tutorial code!

Is that still the case for others?
Can you compare your app to the example solution?
