AMF Login DuplicateSessionDetected

I am trying to create a proof of concept that will maybe get me a job in porting a AIR/Flex project. Trying to login to the server gives a Duplicate Session error. Here is the Royale code:

```

```

Here is my asconfig:
```
{
"compilerOptions": {
"targets": [
"JSRoyale"
],
"source-path": [
"src"
]
},
"additionalOptions": "+configname=flex",
"mainClass": "Main"
}
```

I am starting chrome like this bypass CORS errors:
`chrome.exe --user-data-dir="C://chrome-dev-disabled-security" --disable-web-security --disable-site-isolation-trials`

I get this response:
Duplicate HTTP-based FlexSession error: A request for FlexClient '585E2208-67F8-C428-0452-65840DD101A8' arrived over a new FlexSession 'ECD144ED710A291AE3E5C1D17560B501', but FlexClient is already associated with FlexSession '42A03B06B6FA9FED2AC03F7B3E14DB73', therefore it cannot be associated with the new session.

Loging at network trafic I see 3 requests all with diferent JSSESSIONID:

Any help in solving this is much appreciated, thank you

Start with the Royale code in the issue, especially SecureAMFChannel, RoyaleClient.id, ChannelSet, and the /RiaService/messagebroker/amflongpolling endpoint. Reproduce the login while inspecting the three network requests and their differing JSSESSIONID values, then trace how FlexClient and FlexSession are associated. Done means identifying whether the duplicate-session response comes from the client setup or the server interaction and documenting a verified fix.
