Class 'Prisma' incorrectly extends base class 'Prisma'.

Bug Report

Current behavior
After trying to compile typescript, I get the following error:

src/generated/prisma.ts(6790,14): error TS2415: Class 'Prisma' incorrectly extends base class 'Prisma'.
  Types of property 'query' are incompatible.
    Type 'Query' is not assignable to type 'QueryMap'.
      Index signature is missing in type 'Query'.

Reproduction

If your problem can be reproduced with a certain service definition, please create a new GitHub repository with the reproduction instructions.

You can reproduce this issue by deploying a Prisma API and visiting generated/prisma.ts. The issue is found near the bottom. IE:

// Error here
public query: Query = {
  // etc, not relevant
}

When hovering over query, due to red underline, this is the error notice:

Property 'query' in type 'Prisma' is not assignable to the same property in base type 'Prisma'.
  Type 'Query' is not assignable to type 'QueryMap'.
    Index signature is missing in type 'Query'.

More on repro later

Expected behavior?
Types should play nicely again. We're all friends. Let's all just be friendly.

How can I reproduce this?

Sorry man. I'll try to have an isolated repro today

Thanks! 😄

I got the same error and made an example repository: SpaceK33z/prisma-typescript-error.

A workaround for now is to disable strictFunctionTypes in your tsconfig.json.

This seems to have something to do with a change in prisma-binding or graphql-binding not properly propagated into the static binding generators. Either way, this should be moved to https://github.com/graphql-binding/graphql-static-binding.

Thank you all, I reported the issue here: graphql-binding/graphql-static-binding#69.

odd, strictFunctionTypes: false doesn't seem to mask this issue for me.
