This error is originated from a package error on hdwallet and it happens generally when multiple HDWalllets instances run inside promises.

To fix, change in the file: node_modules/@truffle/hdwallet-provider/dist/index.js

The class to this:

class HDWalletProvider { // ALERT: the construct is not modified and did not fit here so I removed initialize() { return new Promise((resolve, reject) => { this.engine.sendAsync({ jsonrpc: "2.0", id: Date.now(), method: "eth_chainId", params: [] }, // @ts-ignore - the type doesn't take into account the possibility // that response.error could be a thing (error, response) => { if (error) { reject(error); return; } else if (response.error) { reject(response.error); return; } if (isNaN(parseInt(response.result, 16))) { const message = "When requesting the chain id from the node, it" + `returned the malformed result ${response.result}.`; reject(message); } this.chainId = parseInt(response.result, 16); resolve(); }); }); } // ALERT: the checkBIP39Mnemonic is not modified and did not fit here so I removed // ALERT: the ethUtilValidation is not modified and did not fit here so I removed async send(payload, // @ts-ignore we patch this method so it doesn't conform to type callback) { try { await this.initialized; this.engine.sendAsync(payload, callback); } catch (error) { callback(error); } } async sendAsync(payload, callback) { try { await this.initialized; this.engine.sendAsync(payload, callback); } catch (error) { callback(error); } } getAddress(idx) { if (!idx) { return __classPrivateFieldGet(this, _HDWalletProvider_addresses, "f")[0]; } else { return __classPrivateFieldGet(this, _HDWalletProvider_addresses, "f")[idx]; } } getAddresses() { return __classPrivateFieldGet(this, _HDWalletProvider_addresses, "f"); } static isValidProvider(provider) { if (!provider) return false; if (typeof provider === "string") { const validProtocols = ["http:", "https:", "ws:", "wss:"]; const url = url_1.default.parse(provider.toLowerCase()); return !!(validProtocols.includes(url.protocol || "") && url.slashes); } else if ("request" in provider) { // provider is an 1193 provider return true; } else if ("send" in provider) { // provider is a "legacy" provider return true; } return false; } }
