prisma-client provider can't be used with multiple generators

When running the generate command I get an error:

│ Loaded Prisma config from ".....\prisma.config.ts".
│ Prisma config detected, skipping environment variable loading.
│ Prisma schema loaded from prisma\schema
│ Error: Generator "Prisma Json Types Generator" requires generator "prisma-client-js", but it is missing in your schema.prisma.
│ Please add it to your schema.prisma:
│
│ generator gen {
│   provider = "prisma-client-js"
│ }

This is my main schema:

generator client {
  provider        = "prisma-client"
  output          = "../generated"
  binaryTargets   = ["native"]
  previewFeatures = ["prismaSchemaFolder"]
}

generator json {
  provider = "prisma-json-types-generator"
}

datasource db {
  provider = "postgresql"
  url      = env("DATABASE_URL")
}

generator client {
  provider        = "prisma-client"
  output          = "../generated"
  binaryTargets   = ["native"]
  previewFeatures = ["prismaSchemaFolder"]
}

generator json {
  provider = "prisma-json-types-generator"
}

datasource db {
  provider = "postgresql"
  url      = env("DATABASE_URL")
}

The issue is caused by the generator json since when I remove it, it works normally, but I want to use this feature for JSON field type-safety.

subscription tracked returns a 3-tuple to frontend instead of object

I am using tracked as per recommendation in https://trpc.io/docs/server/subscriptions#tracked like this:

for await (const [eventData] of iterable) {
    yield tracked(eventData.jobId, eventData);
  }

for await (const [eventData] of iterable) {
    yield tracked(eventData.jobId, eventData);
  }

It's properly typed on both frontend and backend, eg:

{
    id: string;
    data: someObject;
}

{
    id: string;
    data: someObject;
}

however what I actually receive on frontend is an 3-tuple [id, data, null]. I tried this both on versions "11.0.0-rc.666" and next and got the same results.
