Prisma interactive transactions API error: "Argument of type 'x' is not assignable to parameter of type 'PrismaPromise<any>[]'"

Bug description

See discussion in the prisma chat: https://prisma.slack.com/archives/CA491RJH0/p1628865496360000

A simple update query inside the transaction gives me an error: Argument of type '() => Promise<Integration>' is not assignable to parameter of type 'PrismaPromise<any>[]'.

const trans = await this.prisma.$transaction(async () => {
	return this.prisma.integration.update({
		data: {
			...
		},
		where: {
			id: integration.id
		}
	});
});

I do have the preview feature on: previewFeatures = ["orderByRelation", "referentialActions", "interactiveTransactions"], also I did a generate.

How to reproduce

Simple query like:

const trans = await this.prisma.$transaction(async () => {
	return this.prisma.integration.update({
		data: {
			...
		},
		where: {
			id: integration.id
		}
	});
});

### Expected behavior

Not to show me the error

### Prisma information

```js
model Integration {
    id                        String   @id @db.VarChar(255)
    integrationMethodId       String   @db.VarChar(255)
    name                      String   @db.VarChar(255)
    username                  String   @db.VarChar(255)

    createdAt                 DateTime @default(now()) @db.Timestamptz
    updatedAt                 DateTime @updatedAt @db.Timestamptz

Hey @Rykuno, I looked into the latest release code. You probably just need to add interactiveTransactions to the preview features in your schema.prisma file. This is not documented but is required.

generator client {
  provider = "prisma-client-js"
  previewFeatures = ["interactiveTransactions"]
}

Cheers!

Hey! Yes I did add add the preview feature, db push and try a few things but I’m not sure exactly what fixed it as I threw a bunch of solutions at once at the issue. It might just be my vscode being weird. One of those solutions i mentioned sure worked lol!

Just to clarify the transaction actually worked, just the ts typings were throwing linting errors

Marking this issue as resolved. Feel free to re-open or ping me if you encounter this again. Please make sure that you have regenerated your Prisma Client after enabling the preview flag and restarted your TS server (or VSCode).
