Call static resource from another filter

[germanicus9]

I have these two filters:
SpaWebFilter and
OAuth2ReactiveRefreshTokensWebFilter
On the OAuth2ReactiveRefreshTokensWebFilter I manage refresh tokens. However in the idle mode I want to reload de home page and start login again.
I tried to call the home page from OAuth2ReactiveRefreshTokensWebFilter:
.onErrorResume(e -> initiateReAuthentication(exchange));

private Mono<Void> initiateReAuthentication(ServerWebExchange exchange) { return new SpaWebFilter().filter(exchange.mutate().request(exchange.getRequest().mutate().path("/").build()).build(), chain) }
or directly
return exchange.mutate().request(exchange.getRequest().mutate().path("/index.html").build()).build().

Unfortunately doesn't work even when I start the application the SpaWebFilter loads the static resource. Where is the difference?
Please support.
