Transaction simulation failed: This transaction has already been processed.

[Andross96]

Hello,

When trying to use Drift SDK to place a perp order, I randomly have the following error, even if the perp order is correctly placed :

Error: Simulation failed.
Message: Transaction simulation failed: This transaction has already been processed.
Logs:
[].
Catch the SendTransactionError and call getLogs() on it for full details.
at pQ.sendEncodedTransaction (.next/server/chunks/[root-of-the-server]__dadf0127..js:8:67131)
at async pQ.sendRawTransaction (.next/server/chunks/[root-of-the-server]__dadf0127..js:8:66650) {
signature: '',
transactionMessage: 'Transaction simulation failed: This transaction has already been processed',
transactionLogs: []
}

Here is my code :

// DriftClient init:
const provider = new AnchorProvider(
	connection,
	wallet,
	{
		commitment: 'confirmed',
		preflightCommitment: 'confirmed',
		skipPreflight: false,
	}
);

const driftPublicKey = new PublicKey(sdkConfig.DRIFT_PROGRAM_ID);
const driftClient = new DriftClient({
	connection: provider.connection,
	wallet: provider.wallet,
	programID: driftPublicKey,
	accountSubscription: {
		type: "websocket",
	}
});
await driftClient.subscribe();

// Perp placing order
try {
	await driftClient.placePerpOrder(
		getMarketOrderParams({
			marketIndex: marketIndex,
			baseAssetAmount: assetAmount,
			direction: direction,
		}),
		undefined,
		subAccountId
	);
} catch (e) {
	if (e instanceof SendTransactionError) {
		console.error(e.logs);
	}
	throw e;
}

I'm using NextJS 16 and latest @drift-labs/sdk 2.157.0-beta.7.
Can you please advice.
