Payload from HttpNode changed in 0.20 when posting a FormData

[marcioluis]

What are the steps to reproduce?

I have a Angular app that POST a manually build FormData to a HttpNode in NodeRed with a file as Base64 encoded. Something like this.

uploadImaged(dadosImaged: UploadImaged): Observable<HttpEvent<Imaged>> {
    const url = `${environment.NODE_RED_URL}/uploadImaged`;
    let body = new FormData();
    body.set('codTipoDoc', `${dadosImaged.codTipoDoc}`);
    body.set('descricao', dadosImaged.descricao);
    body.set('file', dadosImaged.file);
    body.set('filename', dadosImaged.filename);
    body.set('indices', JSON.stringify(dadosImaged.indices));
    const req = new HttpRequest('POST', url, body, { reportProgress: true });
    return this.http.request<any>(req).pipe(catchError(this.errorHandler));
}

What happens?

Until version 0.19.X the PAYLOAD of HttpNode was show as a buffer or a raw string in debug node.
In version 0.20.X when POSTing to HttpNode an exception is raised. TypeError: invalid media type.
Activating the flag Accept file uploads? the payload is parsed but I need the buffer version to make an HttpRequest to another backend.

Example:
Evidence Image/imgur

What do you expect to happen?

Payload should be a buffer formdata like in version 0.19
