Stack traces not showing up


I have up and running in my Angular project. I followed the documentation and the created issues all look fine. With one exception: I don’t have a stack trace.

Is it because I am just having the Developer Plan or is it a configuration issue?

public setup(): void {
        release: environment.version,
        attachStacktrace: true,
        debug: !environment.production,
        environment: environment.production ? 'PRODUCTION' : 'DEV',
        dsn: environment.sentry

public captureException(error: any): string {
    return Sentry.captureException(error.originalError || error);

Update: It looks like, that after a deployment to a real domain the stack trace shows up. Is there any restriction on logging the stack trace for http://localhost:4200?
