Turborepo - no type safety when using drizzle in other modules

Hi all, I am setting up a monorepo with turborepo where I have an API under apps/api and a database module under packages/db. I am losing type safety when importing the db instance in another package. I export all of my tables and the drizzle instance like so below: 
// packages/db/src/index.ts
import "@dotenvx/dotenvx";
import { drizzle } from "drizzle-orm/libsql";
import * as schema from "./schemas"; // barrel file to export all schemas and types

if (!process.env.DATABASE_URL) {
    throw new Error("DATABASE_URL not set");
}

export const db = drizzle({
    connection: {
        url: process.env.DATABASE_URL,
        authToken: process.env.AUTH_TOKEN,
    },
    schema,
});
export * from "drizzle-orm";
export * from "./schemas";
// packages/db/src/index.ts
import "@dotenvx/dotenvx";
import { drizzle } from "drizzle-orm/libsql";
import * as schema from "./schemas"; // barrel file to export all schemas and types

if (!process.env.DATABASE_URL) {
    throw new Error("DATABASE_URL not set");
}

export const db = drizzle({
    connection: {
        url: process.env.DATABASE_URL,
        authToken: process.env.AUTH_TOKEN,
    },
    schema,
});
export * from "drizzle-orm";
export * from "./schemas";
I am not sure if this is a problem with my tsconfig for both of these modules or how I am exporting packages. I attached screenshots of what my IDE displays when I hover over users and what the returned value should be. Any help would be appreciated, thank you 🙏

so it was a tsconfig issue, if anyone stumbles across this in the future, this is the tsconfig I have setup 
{
  "$schema": "https://json.schemastore.org/tsconfig",
  "compilerOptions": {
    "esModuleInterop": true,
    "skipLibCheck": true,
    "target": "ES2022",
    "lib": ["ES2022"],
    "allowJs": true,
    "resolveJsonModule": true,
    "moduleDetection": "force",
    "isolatedModules": true,
    "incremental": true,
    "disableSourceOfProjectReferenceRedirect": true,
    "tsBuildInfoFile": "${configDir}/.cache/tsbuildinfo.json",
    "strict": true,
    "noUncheckedIndexedAccess": true,
    "checkJs": true,

    "outDir": "${configDir}/dist"
  },
  "exclude": ["node_modules", "build", "dist"]
}
