React + FontAwesome + Bootstrap - reactjs

I am attempting to learn React and Bootstrap at the same time. I am a beginner.
My issue is that I am trying to display a FontAwesome icon within a React application using the FontAwesome component. I have a Pro license for FontAwesome and have followed their directions on setting up the dependencies. My package.json contains the following:
"dependencies": {
"#fortawesome/fontawesome-pro": "^5.15.4",
"#fortawesome/fontawesome-svg-core": "^1.2.33-beta1",
"#fortawesome/pro-regular-svg-icons": "^6.0.0-beta1",
"#fortawesome/react-fontawesome": "^0.1.15",
"#testing-library/jest-dom": "^5.14.1",
"#testing-library/react": "^11.2.7",
"#testing-library/user-event": "^12.8.3",
"bootstrap": "^5.1.1",
"react": "^17.0.2",
"react-bootstrap": "^1.6.3",
"react-dom": "^17.0.2",
"react-router-dom": "^5.3.0",
"react-scripts": "4.0.3",
"web-vitals": "^1.1.2"
},
When I attempt to use an icon in a component like below:
import { FontAwesomeIcon } from "#fortawesome/react-fontawesome";
import { faUser } from "#fortawesome/pro-regular-svg-icons";
function Header(){
return (
<header>
<h1>My Header</h1>
<FontAwesomeIcon icon={faUser} color="red" size="6x" />
</header>
)
}
export default Header
I get an error:
Error: Cannot find module '#fortawesome/free-solid-svg-icons'
When I review the error bodies below the header they all seem to point to bootstrap.

I have looked through my project which is still small because I am just beginning and I can't find any reference to the Free icons for FontAwesome. I am at a loss and not sure what to even ask. Is there a reference to the free icons within the Bootstrap React component?

According to FontAwesome's React documentation, you need to install #fortawesome/free-solid-svg-icons, too, before adding additional styles.
Run npm i --save #fortawesome/free-solid-svg-icons and try again.

TypeError: render is not a function while using React Context along with React Router

I need to set up a user state that can be called from different components. This setup uses React Router and React Context.
The React context contains just a single state that keeps track of the user's name.
At the top-level i.e App I have passed all the children on to the provider. But I get an error
TypeError: render is not a function
My UserContext code:
const UserContext = createContext();
export const UserProvider = (props) => {
const [user, setUser] = useState("");
return (
<UserContext.Provider value={[user, setUser]}>
{props.children}
</UserContext.Provider>
);
};
export default UserContext;
My App code :
function App() {
return (
<UserProvider>
<Router>
<div>
<Nav />
<Switch>
<Route exact path="/" component={Signup} />
<Route exact path="/signin" component={SignIn} />
<Route path="/register" component={UserRegister} />
<Route path="/homepage/:user" component={Homepage} />
</Switch>
</div>
</Router>
</UserProvider>
);
}
export default App;
The entrie error log:

Upgrading react-scripts to 4.x.x breaks my app

I have been developing a frontend app using React (v16.44.0, cannot upgrade to v17 yet due to a dependency), react-scripts v3.4.4, Typescript (v3.9.9) and React-Bootstrap (v1.5.1) for a few months and all is going well.
However, react-scripts have been updated recently to a v4, and upgrading breaks the whole app. I am concerned with securities issues with react-scripts v3. I also would like to upgrade Typescript to v4+, there seem to be an incompatibility btw Typescript 4 and react-scripts 3 related to eslint. Various deprecation warnings are also stacking up.
When I enable react-scripts v4.0.3, run npm start to launch the development server, Firefox (v78.8) throws:
"ReferenceError: SharedArrayBuffer is not defined" in "node_modules/webidl-conversions/lib/index.js:347".
Apparently webidl-conversions is required by bootstrap. I have searched about the SharedArrayBuffer issue, apparently it requires enabling additional headers, but I could not find how to add them using the npm start webserver.
[Edit: upgraded Firefox to v86, still have the issue but I have not tried to configure it yet.]
If I try with Chrome (v89), I have:
"TypeError: Cannot convert undefined or null to object" on "node_modules/whatwg-url/dist/utils.js:48"
which also seem to be required by Bootstrap.
I do not have a dependency on Bootstrap per se, I use the react-bootstrap implementation. However, I use bootstrap-scss for the (S)CSS part.
I can upload full stack traces if needed. Here is my package.json:

It's hard to tell exactly without your full package.json, but it seems that it's not related to the update of react-scripts itself, but instead probably an updgrade on another library that you are depending on that uses SharedArrayBuffer which is not supported in Firefox v78
Edit: OP found out that the problematic package was react-sketch
As per the other error, it seems to be related, but don't know exactly why it happens. Anyhow, found this issue in their Github page and one suggestion is to upgrade jsdom to version >=16.3 (if you are using it)
Did you apply each migration described in the changelog?
They also suggest you delete node_modules if you break your app when updating from 3.4 to 4.
NOTE: You may need to delete your node_modules folder and reinstall your dependencies by running yarn (or npm install) if you encounter errors after upgrading.
Try deleting it and running npm install
You can download Bootstrap CSS files manually and save them in project files.
Try:
Deleting your node_modules and package-lock.json
// This normally fixes my issue when going back to old react projects
npm cache clean --force
run npm install
run npm run start

received Error: failed to invert matrix when add in deckGL in Reactjs hooks

im new in reactjs and deckGL and im having a little problem with the code below. I am trying to add DeckGL with FlyToInterpolator to center the marker. I'm receiving this error after I clicked the button, but when i'm using the react-map-gl + FlyToInterpolator it works.
update: the issue is, I having a problem when using FlyToInterpolar API in deckGL, but I have no issue using FlyToInterpolar in react-map-gl.
Please help! thank you very much
p/s: sorry english is not my main language.

TypeError: Unable to set property 'props' of undefined or null reference [duplicate]

This question already has an answer here:
React-router: TypeError: Cannot set property 'props' of undefined
(1 answer)
Closed 3 years ago.
I m not able to figure out how to resolve this error previously it was not there.If m trying to make constructor.
Previously i have imported React twice
import React from 'react';
import React,{Component} from 'react';
because of which error was there. To correct it i have removed 1 import from the code.
import React,{Component} from 'react';
import './App.css';
class App extends Component() {
constructor(props){
}
render() {
return (
<div className="App">
<table className="titleBar">
<tbody>
<tr>
<td>
<img alt="app icon" width="50" src="primary_green.svg"/>
</td>
<td width="8"/>
<td>
<h1>MovieDb Search</h1>
</td>
</tr>
</tbody>
</table>
<input style={{
fontSize: 24,
display: 'block',
width: '99%',
paddingTop: 8,
paddingBottom: 8,
paddingLeft: 16
}} placeholder="Enter Search Term"/>
</div>
);
}
}
export default App;

When defining your App you are invoking Component as a function. Change
class App extends Component() {
to
class App extends Component {
Besides, it makes sense to remove the constructor if it is just empty.

I tried several manipulations : remove my node_modules and package-lock.json and re-install the application. I tried a newer version of accordion too and no solution worked for me.
Any Idea ?
I added the babel librairies and that resolved my problem:
"babel": "^6.23.0",
"babel-core": "^6.26.3"
