This is the code of the module (btw dont mind but th "ok" its for testing.
const router = require("express").Router();
const User = require("../models/User")
//REGISTER
router.get("/register", async (req,res)=>{
const user = await new User({
username:"john",
email:"john#gmail.com",
password:"123456"
})
await user.save();
res.send("ok");
});
module.exports = router
the syntax is right, needed to format it for containing on the "code" on the question.
Thanks in advance, Francesco

You are trying to call the model without even establishing a connection with the database. You need to use async/await with connect() or createConnection().

How can I solve login error on discord.js [duplicate]

Dont know how to fix it. I tried and investigate on the documentation but cant find the solution.
I've added this line to my code to find the error:
process.on('unhandledRejection', error => {
console.error('Unhandled promise rejection:', error);
});
Getting this:
{ code: 500, method: 'get', path: '/gateway/bot', requestData:
{ json: undefined, files: [] } }

The AbortController package was introduced in Node.js v16 (?). So you need to upgrade your Node.js version. Discord.js v13 requires you to use Node.js v16 and higher as stated in their documentation.
Depending on your operating system, you can either install 64bits or 32bits version of Node.js. Head over to the official website and download 16.8.x (Current, Latest Features) Windows installer.
After installation, verify the version by typing node -v in your console.

Errors with compiling Zig to wasm32-freestanding

I am trying to compile Zig functions to a freestanding WebAssembly module using the wasm32-freestanding target. The official documentation has a section explaining how to do this, but with a recent version of Zig (0.8.0) I get errors when trying to instantiate the resulting module with JavaScript.
// file: main.zig
export fn add(a: i32, b: i32) i32 {
return a +% b;
}
// file: test.js
WebAssembly.instantiate((function() {
const source = require("fs").readFileSync("main.o");
return new Uint8Array(source);
})(), { env: {} }).then(wasm => {
const add = wasm.instance.exports.add;
console.log(add(1, 2));
});
$ zig version
0.8.0
$ node --version
14.17.3
$ zig build-obj main.zig -target wasm32-freestanding -dynamic -OReleaseFast
$ wc -c main.o # the generated code has extension `.o` instead of `.wasm`
135
$ node test.js

Inspecting the generated wasm module shows that it attempts to import a value called __linear_memory from the scope env. Naturally this fails as I am not providing such an import. However, the example project zig-wasm-test includes a WASM module (compiled with an old version of Zig) which does not include these imports.
What am I doing wrong here? Should I just be providing a __linear_memory export to the module even though it isn't used?

You should try using build-lib instead of build-obj.

I am not sure how to run the node --trace-warnings. Looks like it a serialization issue, even it is just a warning but not sure where is the issue. Is there any better way to find the exception

Run jest with --detectOpenHandles. This will show you what is actually wrong with your test spec. For me, there were missing Angular Material imports and service mocks. You may be prompted to add the BrowserAnimationsModule, as Nambi alluded to in his answer
package.json:
"test": "jest --detectOpenHandles"

This message usually appears, if there is an error, that does not resolve into a standard exception.
As mentioned by #JamesBarret using jests detect open handle feature will provide you with a nice error message, telling you what the real problem behind this message is.
The handle --detectOpenHandles mentioned in the other message is deprecated though and was replaced with --detect-open-handles.
You can just use: (on your cli)
jest --detect-open-handles
Or in a package.json file:
"test": "jest --detect-open-handles"
Or as it was in my case an angular test:
ng test --detect-open-handles

Adding my answer to help someone if missed.
In my case i have missed to import
import { BrowserAnimationsModule } from '#angular/platform-browser/animations';
Able to find the issue only when running one of the test case in isolation.

The issue was with the async operation, so writing the test case with below, solve the issue for me
describe('DateSelectionComponent', () => {
let component: DateSelectionComponent;
let fixture: ComponentFixture<DateSelectionComponent>;
beforeEach(async(() => {
TestBed.configureTestingModule({
declarations: [DateSelectionComponent, SafePipe],
imports: [
SharedModule,
NgReduxTestingModule,
RouterTestingModule.withRoutes([])
],
providers: [
{
provide: PageAPIActions, useValue: { setPageState() { } }
}
]
}).compileComponents();
fixture = TestBed.createComponent(DateSelectionComponent);
component = fixture.componentInstance;
// Don't use Object.defineProperty when assigning value to class properties
component.page$ = of('value');
component.page = { destination: 'value' };
component.startDate = new NgbDate(2019, 2, 27);
component.minDate = new NgbDate(2019, 2, 27);
fixture.detectChanges();
}));
it('should create', () => {
expect(component).toBeTruthy();
});
it('Should Match Snapshot', () => {
expect(fixture.debugElement.nativeElement).toMatchSnapshot()
});
});

In my situation, the cryptic error was triggered by not importing HttpClientModule into the test file. More details here.

I had this same issue when running jest with --watch. Removing --watch stopped the error.

Looks like the error is due to some async operation being done. Try wrapping your unit test inside a waitForAsync function.
