Here is the issue:
useUser is failing during the npm run build the error given is:

React Hook “useUser” is called in function “members” that is neither a React function component nor a custom React Hook function

Here are the dependencies and versions of the application

"dependencies": {
    "@auth0/nextjs-auth0": "^3.0.0",
    "@prisma/client": "^5.0.0",
    "@types/auth0": "^3.3.3",
    "@types/node": "20.4.5",
    "@types/react": "18.2.17",
    "@types/react-dom": "18.2.7",
    "@vercel/postgres": "^0.4.1",
    "autoprefixer": "10.4.14",
    "cloudinary-react": "^1.8.1",
    "dotenv": "^16.3.1",
    "eslint": "8.46.0",
    "eslint-config-next": "13.4.12",
    "next": "13.4.12",
    "postcss": "8.4.27",
    "react": "18.2.0",
    "react-dom": "18.2.0",
    "react-intersection-observer": "^9.5.2",
    "tailwindcss": "3.3.3",
    "typescript": "5.1.6"
  },

This is the part of the code where the build fails

import React from "react";
import { useUser } from "@auth0/nextjs-auth0/client";
import NavbarMembers from "@/components/navbar/navbar-members";
import Image from "next/image";
import Link from "next/link";

export default function members() {
     const { user, error, isLoading } = useUser();

     //let isLoading = false;
     //let error = { message: "" };
     //let user = { name: "Demo User", picture: "" };

     if (isLoading) return <div>Loading...</div>;
     if (error) return <div>{error.message}</div>;

     if (user) {
          let imageUrl;
          if (user.picture) {
               imageUrl = user.picture;
          } else {
               imageUrl =
                    "https://res.cloudinary.com/fbchb/image/upload/v1690661226/blankUserImage_ro3xp5.png";
          }
          return (

Any help is much apprecaited.
Thanks,

I had issues with the useUser hook during build time as well. I am on nextjs 14 though so it might be different.
The error was that I wasn’t using the ‘use client’ pragma at the top of the file that had this chunk of code.
That might be the issue for you too!
