Websocket reconnection failure with NodeJs 22.X

[osan15]

There seems to be a problem with the automatic reconnection of the WebSocket client on the NodeJS 22 version.

const provider = new WsProvider('ws://127.0.0.1:9944');
const api = await ApiPromise.create({ provider });
api.on('disconnected', () => {
  console.log(`Disconnected`);
});
api.on('connected', () => {
  console.log(`Connected`);
});
api.on('error', (err) => {
  // When the API is disconnected, it will emit an error event

  console.error(err);
 // ErrorEvent {
 //   type: 'error',
 //   defaultPrevented: false,
 //   cancelable: false,
 //   timeStamp: 9766.533212
 //  }

console.error(err.message);
// Received network error or non-101 status code.
});

When I stop the blockchain node, I receive an error event in the “error” listener.
When the node is restarted, the WebSocket client is never reconnected.

Versions :

NodeJS version : 22.12
"@polkadot/api": "^15.1.1"

The same code downgraded to NodeJS version 20.18.2 does not trigger this issue.

I found similar issues with other packages :

Has anyone experienced this bug ?
