client.on('error') doesn't emit errors while errors are visible in 'debug' logs

[HarryVGI]

Describe the bug

The client.on('error', (error: Error) => {}) event handler is no longer emitting errors. However, the errors can still be observed when using client.on('debug', (msg: any) => {}).

Versions

Using steam-user version 5.2.0 and node version 22.11.0.

Code

const client = new SteamUser({
  httpProxy: getProxyUrl(),
});
client.on('debug', (msg: any) => console.log(msg));
const loggedOnPromise = new Promise<any>((resolve, reject) => {
  client.on('error', (error: Error) => {
    console.log(`Error from SteamUser: ${error?.name} - ${error?.message}`);
    reject(error);
  });
  console.log(`Added error listener to SteamUser`);
  client.on('loggedOn', () => {
    console.log(
      `Logged into Steam as anon: ${this.currentId}; with public IP ${this.currentPublicIp}`
    );
    resolve(client);
  });

  client.on(
    'disconnected',
    (eresult: EResult, msg?: string | undefined) => {
      console.log(
        `logged off anon user with EResult ${eresult}(${SteamEResult.getName(
          eresult
        )}) reason '${msg}'`
      );
    }
  );

});

client.logOn({ anonymous: true });

This is expected behavior, it continually re-attempts to connect if it encounters a network error while connecting.

[HarryVGI]

Hmm, interesting. Then that's where I have the issue -- it's not re-attempting, instead getting stuck with the [WebAPI] Using cached value for API_GET_https://api.steampowered.com/ISteamDirectory/GetCMListForConnect/v0001/ line.

So, I'm waiting for the loggedOn event, but when it gets an error like this, then it just gets stuck on that last debug line.
