captureException with the js sdk in Angular

There is a lot of captureException and incomprehensible (like “Object.s” as title ) errors in Sentry

There is my configuration

    "@angular/animations": "^8.0.0",
    "@angular/cdk": "^8.0.0",
    "@angular/common": "^8.0.0",
    "@angular/compiler": "^8.0.0",
    "@angular/core": "^8.0.0",
    "@angular/forms": "^8.0.0",
    "@angular/material": "^8.0.0",
    "@angular/platform-browser": "^8.0.0",
    "@angular/platform-browser-dynamic": "^8.0.0",
    "@angular/platform-server": "^8.0.0",
    "@angular/router": "^8.0.0",
    "@sentry/browser": "^5.11.2",

in my main. module.ts:

    Sentry.init({
        dsn: 'BLABLABLA',
        release: environment.version,
        environment: environment.production === true ? 'production' : 'staging'
    });

...

export class SentryErrorHandler extends ErrorHandler {

    constructor() {
        super();
    }

    handleError(err: any): void {
        if (environment.production === true || environment.preprod === true) {
            Sentry.captureMessage(err.originalError || err);
        }
        throw err;
    }
}
...

 providers: [
        {provide: ErrorHandler, useClass: SentryErrorHandler},
...

I changed from Sentry.captureException to Sentry.captureMessage but the problem is still present.

Screenshot of the exceptions thrown:

There is a “synthetic error” thrown in the sentry sdk code base.

Everything is configured as the documentation mention it, I also upload the sourcemaps correctly.
