typescipt enum is stored as string in model

Overview of the issue

I can't compare the speechToTextJob.status with the static enum values JobStatus.* because the field is set to string values.

Motivation for or Use Case

We use Angular 5 in the frontend. I want to test the status field of the incoming data in the onSuccess method of speech-to-text-job.component.ts. Because the incoming data is of type String but model has the enum type, I have to cast the field to compare it to a String.

Reproduce the error

in speech-to-text-job.component.ts add this to onSuccess:

        if (this.speechToTextJobs.find((item) => item.status === JobStatus.WAITING || item.status === JobStatus.PENDING)) {
            Observable.timer(2000).first().subscribe(() => this.loadAll());
        }

Timer is never started.
