prisma.$transaction(async (prisma) => { ... }) not allowed by typescript definitions

Bug description

The prisma.$transaction(PrimsaPromise[]) method is included in the typescript definition for the client, but prisma.$transaction((prisma: PrismaClient): Promise) is not.

How to reproduce

In any typescript project:

prisma.$transaction(async (prisma) => {})

Run tsc -d

Result:

app/models/organization.server.ts:70:30 - error TS2345: Argument of type '(prisma: any) => Promise<any>' is not assignable to parameter of type 'PrismaPromise<any>[]'.
  Type '(prisma: any) => Promise<any>' is missing the following properties from type 'PrismaPromise<any>[]': pop, push, concat, join, and 28 more.

70   return prisma.$transaction(async (prisma) => {
                                ~~~~~~~~~~~~~~~~~~~

Expected behavior

It should include the prisma.$transaction: (prisma: PrismaClient): Promise type in the type definition file, since it exists in the code as well.

Ah, I see it is at https://www.prisma.io/docs/concepts/components/prisma-client/transactions#the-transaction-api, but buried a bit. I got as far as “there are two ways”, tried one, it didn’t work, so came here.

Could add a note on that second bullet like “This requires additional config to enable, see below.”

@Ustice @isaacs does adding previewFeatures = ["interactiveTransactions"] and then regenerate your Prima client with npx prisma generate fix your issue?
