In version above rc9 league client is never found

Hi, is this issue different from #106?

[janerjak]

I might add to this.

Have been running into the same issue. When using rc10 or above, neither an existing nor a newly launched LeagueClient is discovered (using authenticate / web sockets). Downgrading to rc9 worked for me. Since r10 is also not working, this is probably unrelated to Get-CimInstance, but not sure.

Tried running Node.js as Administrator, but that didn't resolve this.
Any idea what the cause is? Please tell me, if there is something else I should provide.

Code with awaitConnection: true

console.log("Looking for League client");
clientCredentials = await authenticate({
	awaitConnection: true,
	pollInterval: 1000,
});
console.log("Obtained League client credentials:", clientCredentials);

Results with League client running:

On rc11, rc10

On rc9

Code with awaitConnection: false

console.log("Looking for League client");
clientCredentials = await authenticate();
console.log("Obtained League client credentials:", clientCredentials);

Results with League client running:

On rc11, rc10

On rc9

System details

Windows 11 22H2
Node.js v18.15.0

yes, exactly as Janerjak is saying. Its not related to #106. After upgrading version to above rc9 it cant find process of LeagueClientUx. Tried running Get-CimInstance command as well as wmic one from your code and League process is found. I was looking through commits and nothing much changed but dependency versions - maybe there is a problem?

Interesting. I was running on rc10 and rc11 just fine for a while. No longer the case.
I had to revert to rc9 to be able to connect

Maybe Riot changed something in the latest patch?

It's strange that rc10 has also changed the ability to connect to the client, as that update only changed the WebSocket connection. If someone could get the actual error that's thrown instead of just the ClientNotFoundError (should be here https://github.com/matsjla/league-connect/blob/master/src/authentication.ts#L160) that may be able to tell us more about what's going on.

Catching error results in:

TypeError: object null is not iterable (cannot read property Symbol(Symbol.iterator))
    at tryAuthenticate (C:\Users\Sebastian\IdeaProjects\OverLeague\node_modules\league-connect\dist\index.cjs:110:28)
    at process.processTicksAndRejections (node:internal/process/task_queues:95:5)
    at async C:\Users\Sebastian\IdeaProjects\OverLeague\src\main.js:17:23

where 110 line in index.cjs at tryAuthenticate is:

const [, password] = stdout.match(passwordRegex);

[plonsik]

there was an commit #103 which changed regex for getting password
Testing:

• old regex
  

• new regex

Does the patch from Eugene in #108 fix it? Try rc-12
