Extending client not typesafe

I'm working in a NestJS project and need to extend the prisma client to replace all Date with string. I have this code:

import { Injectable, OnModuleInit } from '@nestjs/common';
import { PrismaClient } from '~/types/prisma-schema';

export type WithSerializedDates<T> = T extends Date
  ? string
  : T extends Array<infer R>
    ? Array<WithSerializedDates<R>>
    : T extends object
      ? { [K in keyof T]: WithSerializedDates<T[K]> }
      : T;

export const withoutDates = <T>(model: T): WithSerializedDates<T> =>
  JSON.parse(JSON.stringify(model)) as WithSerializedDates<T>;

@Injectable()
export class PrismaService extends PrismaClient implements OnModuleInit {
  async onModuleInit(): Promise<void> {
    await this.$extends({
      query: {
        $allModels: {
          $allOperations: async ({ query, args }) => {
            return withoutDates(await query(args));
          },
        },
      },
    }).$connect();
  }
}

import { Injectable, OnModuleInit } from '@nestjs/common';
import { PrismaClient } from '~/types/prisma-schema';

export type WithSerializedDates<T> = T extends Date
  ? string
  : T extends Array<infer R>
    ? Array<WithSerializedDates<R>>
    : T extends object
      ? { [K in keyof T]: WithSerializedDates<T[K]> }
      : T;

export const withoutDates = <T>(model: T): WithSerializedDates<T> =>
  JSON.parse(JSON.stringify(model)) as WithSerializedDates<T>;

@Injectable()
export class PrismaService extends PrismaClient implements OnModuleInit {
  async onModuleInit(): Promise<void> {
    await this.$extends({
      query: {
        $allModels: {
          $allOperations: async ({ query, args }) => {
            return withoutDates(await query(args));
          },
        },
      },
    }).$connect();
  }
}

But when using the client, it does not apply the extension types.

Change db url in ctx with an API call

I want to have a switch in my frontend to change from dev db to prod db. I'm using prisma. Have 2 prisma instances (one for prod and the other for dev). Is there any way to override the prisma instance in the ctx with an API call?

Trouble with Vercel and deployment URL

Hey I've been having a problem with nextjs deploying to vercel. In localhost the calls to the backend are done correctly, but when deployed, the calls are made to https://myvercelurl.vercel.app/deployment_url/api/trpc/.... I don't know why the hell the deployment_url is inserted there. Running in npm, packages: @trpc/client: ^10.45.0 => 10.45.1 @trpc/next: ^10.45.0 => 10.45.1 @trpc/react-query: ^10.45.0 => 10.45.1 @trpc/server: ^10.45.0 => 10.45.1 next: 14.1.0 => 14.1.0 react: ^18 => 18.2.0 typescript: ^5 => 5.3.3 If someone could help me I will really appreciate it
