typescript - Path module - Cannot read property of "join" undefined

Question

I'm currently trying to use path.join to join a directory. After it's compiled, it throws an error (surprised typescript didn't pick up on it while compiling)

/media/chen/storage/development/urlshortener/src/database/database.js:9
        filename: path_1["default"].join(__dirname, 'chen.db')
                                    ^
TypeError: Cannot read property 'join' of undefined

Here is database.ts

import knex from 'knex';
import path from 'path';

export const db = knex({
  client: 'sqlite3',
  connection: {
    filename: path.join(__dirname, 'chen.db')
  },
  useNullAsDefault: true
});

And here is the compiled database.js

"use strict";
exports.__esModule = true;
exports.db = void 0;
var knex_1 = require("knex");
var path_1 = require("path");
exports.db = knex_1["default"]({
    client: 'sqlite3',
    connection: {
        filename: path_1["default"].join(__dirname, 'chen.db')
    },
    useNullAsDefault: true
});

In VSCode, there are no errors showing at all, and type definitions work as normal
This is my typescript config https://hastebin.com/okikowabip.json
