[error] provider.getBalance(account) > toLowerCase is not not defined

[saurav2799]

Describe the bug
provider.getBalance is throwing an internal error, when passing Account Address to retrieve account balance. However, ens names are working fine.

exports = async function(arg){
  
  const { ethers } = require("ethers");
  const provider = new ethers.providers.JsonRpcProvider('https://rinkeby.infura.io/v3/xxxxxx')
  
  const account = '0x3D92bA48A174111DAa937B6e07EDd69874C3F898'
  
  const balance = await provider.getBalance(account);
  return ethers.utils.formatEther(balance)
  
};

Reproduction steps
Create a new function via mongodb-realm console.

exports = async function(arg){
  
  const { ethers } = require("ethers");
  const provider = new ethers.providers.JsonRpcProvider('https://rinkeby.infura.io/v3/xxxxxx')
  
  const account = '0x3D92bA48A174111DAa937B6e07EDd69874C3F898'
  
  const balance = await provider.getBalance(account);
  return ethers.utils.formatEther(balance)
};

Environment:
This is running in node + serverless environment. the ethers npm library is installed. serverless environment is provided via mongodb-realm which is running on aws (out-of-the-box)

etherr.js v5.5.4

I used the example from the docs: and that seems to work fine. so how do we pass an account address directly...

ethers.js version: 5.5.4

[saurav2799]

Downgraded ethers.js to 4.0.49 and this is working fine.
it seems to be an internal function call for string conversion which is failing for account/wallet addresses 0x....
