_supabaseClient__WEBPACK_IMPORTED_MODULE_1__.supabase.auth.signIn is not a function

Question

I am trying to sign in to a project I'm working on to test the authentication. Currently, when I try to sign in, I'm met with the error "supabaseClient__WEBPACK_IMPORTED_MODULE_1_.supabase.auth.signIn is not a function"

This is a React project. I'm using Supabase for my authentication. I will include my LogIn.js file (the file housing the log in function) as well as my package.json file so you can see all my dependencies. I cannot for the life of me figure this out haha. Thanks in advance.

LogIn.js:

import React, { useState } from "react";
import { supabase } from "../supabaseClient";
import "./LogIn.css";

const LogIn = () => {
  const [email, setEmail] = useState("");
  const [password, setPassword] = useState("");

  const handleLogIn = async (e) => {
    e.preventDefault();
    const { error } = await supabase.auth.signIn({ email, password });

    if (error) {
      alert(`Error logging in: ${error.message}`);
    } else {
      alert("Login successful!");
    }
  };

  return (
    <div className="auth-form-container">
      <form className="login-form" onSubmit={handleLogIn}>
        <h1>Welcome back to BookSwap</h1>
        <input
          type="email"
          placeholder="Email"
          value={email}
          onChange={(e) => setEmail(e.target.value)}
          required
        />
        <input
          type="password"
          placeholder="Password"
          value={password}
          onChange={(e) => setPassword(e.target.value)}
          required
        />
        <button type="submit">Log In</button>
      </form>
    </div>
  );
};

export default LogIn;

I have tried changing the .signIn to .signInWithPassword, in case I wasn't utilizing the right function based on the library I was using, but that didn't work. I still got the same error, apart from the function it was referencing (sign in vs. sign in with password). I changed the entire LogIn.js function at one point to utilize the supabase OTP method, which worked, but I don't want to utilize a OTP. I want to be able to log in with a username/password.

EDIT

I tried using signInWithPassword again, and it worked. I'm guessing the first time that I did SignInWithPassword (capital S on Sign), and didn't notice.
