Typescript posting coming up as undefined when trying to connect mongoDB

I have the following two files and I'm trying to setup authentication but the incoming request comes up as undefined when I try to pass it through a function.

The code block

console.log(req.params)

Actually gives back the expected results, so if I were to send a request of...

http://localhost:5000/register/banana/john

...it would return

{ user: 'banana', password: 'john' }

but the following

await mongoUser.register(user, password);

I get

TypeError: Cannot read property 'toBSON' of undefined

If this happens to be a typescript specific problem, I apologize in advanced. I'm transitioning over from js so it's possible I'm not specifying a type somewhere.

index.ts

import express, {Request, Response} from 'express';    const app = express();  const cors = require("cors");  const mongoUser = require("./mongoUser.ts");    /**   * This is middleware   */  app.use(cors());  app.use(express.json())    app.post("/register/:user/:password", async (req: Request, res: Response) => {      try {          console.log(req.params) //{ user: 'banana', password: 'john' }          const {user, password} = await req.params;          console.log(user); //banana          console.log(password) //john                  await mongoUser.register(user, password); //error within            res.json("Successfully registered!");      } catch (err) {          console.error(err);      }  })    app.listen(5000, () => {      console.log("server has started on port 5000");  });  

mongoUser.ts

export {};  const {MongoClient} = require('mongodb');  const credentials = require('./mongoAuth.json');  const uri = `${credentials.client}/${credentials.database}?retryWrites=true&w=majority`  const mongoClient = new MongoClient(uri);      module.exports = {        validator: async () => {        },        login: async () => {        },        register: async (user: string, pass: string) => {          await mongoClient.connect();            await mongoClient.db(`${credentials.database}`).collection(`${credentials.collection[0]}`).updateOne(              {                  $push: {                      username: user,                      password: pass                  }              }          )            mongoClient.logout();      },        allUsers: async () => {        },    }
