lazy loading `tronweb` in esm module is resulting in ReferenceError: proto is not defined

[ice-chillios]

Importing tronweb dynamically in esm module sometimes doesn't load proto properly and throws ReferenceError. On my quick check over codebase I could assume it's probably caused by some circular dependencies but would need further confirmation

Code

async function loadTokenInfo(address) {
	const TW = await import("tronweb");
	const tronWeb = new TronWeb({
	  fullHost: "<rpcUrl>",
	  // Set a default address for read-only calls (required by TronWeb)
	  privateKey: "0000000000000000000000000000000000000000000000000000000000000001",
	});
	
	const contract = await tronWeb.contract().at(address);
	
	const [symbolResult, decimalsResult] = await Promise.all([
	  contract
	    .symbol()
	    .call()
	    .catch((error: Error) => {
	      console.warn(`Could not fetch symbol for ${address} on Tron:`, error);
	      return undefined;
	    }),
	  contract
	    .decimals()
	    .call()
	    .catch((error: Error) => {
	      console.warn(`Could not fetch decimals for ${address} on Tron:`, error);
	      return 6;
	    }),
	]);
}

Error

It is a known issue. You can use require instead of import.

It's gonna load on module startup - not on usage, which is necessary there to avoid initial start-up hiccups
