TypeError: Cannot read properties of undefined (reading 'map') at PumpFunParser.parse (C:\Users\Utente\Desktop\testing\node_modules\solana-parser\dist\parser\pumpfun\parser.js:75:32)
Only sometimes, 99% tx are working. I retrieve txs via blockSubscribe:
function connectToSolana() {
ws = new WebSocket(WSS_ENDPOINT);
ws.on("open", () => {
const msg = JSON.stringify({
jsonrpc: "2.0", id: 1, method: "blockSubscribe",
params: [
{ mentionsAccountOrProgram: PUMP_PROGRAM },
{
commitment: "confirmed", encoding: "base64",
showRewards: false,
transactionDetails: "full", maxSupportedTransactionVersion: 0
}
]
});
ws.send(msg);
});
then the msg is elaborated:
ws.on("message", async (data) => {
const parsed = JSON.parse(data);
if (parsed.method !== "blockNotification") return;
const txs = parsed.params.result.value.block.transactions || [];
for (const tx of txs) {
if (!tx.meta || tx.meta.err) continue;
const parser = new PumpFunParser();
const pumpTxn = parser.parse(tx); ///////// error here
.... other logic...
