Ts.ED simple static server surprise 404 failure

Question

I have a SPA who I was developing with Ts.ED and, with I don't know what change, completely stopped serving the static content. I reduced as much as possible the code to even make an exposition repository.

The problem seems that the static routes are not mounted. I even begun to debug Ts.ED code, I have no clue of what went wrong. I'll provide with the main code, the messages, and a git repo for reproduction.

To be fair, it was working so well while I was developing something completely different, that I don't understand what might have happened.

server/index.ts

import { join } from "path";
import { $log, Configuration, Inject, PlatformApplication, Res } from "@tsed/common";
import { PlatformExpress } from "@tsed/platform-express";
import config from '@config';

const rootDir = __dirname;
const clientDir = join(rootDir, '../client');
console.log('clientDir: ' + clientDir);

@Configuration({
    rootDir,
    port: config.http.port,
    statics: {"/": [{root: clientDir}]}
})
export class Server {}

async function bootstrap() {
    try {
        $log.debug("Start server...");
        const platform = await PlatformExpress.bootstrap(Server, {});
        await platform.listen();
        $log.debug("Server initialized");
    } catch (er) {
        $log.error(er);
    }
}

bootstrap();

Finally, it was not a wrong manipulation of mine but a bug who didn't reveal before and was solved (now in version 6.75.7) - So, the solution was ... to update.
