Class 'Prisma' incorrectly extends base class 'Prisma' with strictFunctionTypes

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'.

when "strictFunctionTypes": true is used in tsconfig.json.

Reproduction

Expected behavior?

"strictFunctionTypes": true is supported
