Node cannot compile static initializer block [duplicate]

I've been looking at this error for a long time and I just cannot wrap my head around it.
Here's the code:
class Instance {
static {
}
}
module.exports = Instance;
That is all there is. The class was full of stuff but I deleted them all because they are irrevelant. It's giving the same error with or without them.
The error:
static {
^

I've used static constructors in the past and testing the same code somewhere else seems to work so I dont understand what the issue is here. Please help me.
SOLUTION: Updated Node to 16.13.1 and it now works. 16.7.0 wasnt enough.

It is supported by Node 17.3.0. It is an ES2022 feature. This https://node.green/#ES2022 is a nice link to find ES feature compatibility in Nodejs. You will have to download the current version of Nodejs which is 17.3.0.

React/Next.js doesn't seem to work with Apexcharts

Problem
My Next.js/React/Node app crashes when I import Chart from "react-apexcharts" in any file. Attempting to visit the app results in the following error: Server ErrorReferenceError: window is not definedThis error happened while generating the page. Any console logs will be displayed in the terminal window. (see call stack below). This happens regardless if the imported <Chart/> is rendered in the page or just left unused. Interesting thing is, if I save a file and initiate a Next.js quick refresh, my app begins working as normal (sometimes). But, when I just launch the app and attempt to visit it, or when I manually refresh with f5, the aforementioned error occurs. Basically, it only works after a Next.js quick refresh (and sometimes, presumably randomly, it doesn't work in this scenario either, throwing the same error as before).
Environment
Node.js (14.16.0), React (17.0.2), Express (4.17.1), Next.js (10.2.0), react-apexcharts (1.3.9), apexcharts (3.26.3), Edge Browser, Win10.
Next.js server is integrated together with Express server.
Logging

The above issue appears because you created the next.js app with SSR enabled
To solve this issue, you need to import the apex-charts component dynamically with SSR disabled.
import dynamic from 'next/dynamic'
const Chart = dynamic(() => import('react-apexcharts'), { ssr: false });

You should import it using this :
import dynamic from 'next/dynamic'
const DynamicComponentWithNoSSR = dynamic(
() => import('yourcomponent using react apex-charts'),
{ ssr: false }
)
because of the use of window it's not working with the ssr mode enabled

I get throw new ERR_SERVER_ALREADY_LISTEN(); when I try to run my program with node.js. Am I closing it wrong?

recently I have been using node.js to code something that creates a server on localhost, and when I'm done running it with node, I press control+C to stop it. Then I made some modifications, attempted to run it again, and I get this:
net.js:1399
throw new ERR_SERVER_ALREADY_LISTEN();
^
Error [ERR_SERVER_ALREADY_LISTEN]: Listen method has been called more than once without closing.

Did I close my program wrong and its still running in the background? If so, how do I close it?
Thanks in advance if you help.

Possible issue with multer? Error: Router.use() requires callback

Building a site with yeoman angular-fullstack works great locally, but when I deploy and use the dist/release version it gives me this fun error on my server.
Error: Router.use() requires callback functions but got a [object Object]

It seams that it's failing on this line
router.use(multer({ dest: './public/uploads/'}));
Though it works locally completely fine? Has me a bit stumped.
Wonder if its related to multer? I have the node module installed.
Thoughts?

Recent versions of multer changed the API. If you look at the examples, you will see you now have to do something like:
var upload = multer({ dest: './public/uploads/'});
// ...
router.use(upload.single('foofield'));
Or upload.array() or upload.fields().
