Must enable 'extendedIndexes` preview feature when trying to serve documents

It seems you are using a 3.x of Prisma, as it considers extendedIndexes a preview feature. I am using 4.x Prisma and this is no longer a preview feature. Output of generating the prisma client and docs and then trying to serve:

nathan@Server-Box:~/dev/alliance/ams$ npx prisma generate
Environment variables loaded from .env
Prisma schema loaded from prisma/schema.prisma

✔ Generated Prisma Client (4.8.0 | library) to ./prisma/client in 1.08s

✔ Generated Prisma Docs Generator to ./prisma/docs in 568ms
You can now start using Prisma Client in your code. Reference: https://pris.ly/d/client

import { PrismaClient } from './prisma/client'
const prisma = new PrismaClient()

warn Versions of prisma@4.1.1 and @prisma/client@4.8.0 don't match.
This might lead to unexpected behavior.
Please make sure they have the same version.

nathan@Server-Box:~/dev/alliance/ams$ npx prisma-docs-generator serve

It may be wise to configure the CLI version used based on the project's Prisma version used, if possible.
