ethers.js: How do I call transfer on an ERC20 contract? (missing signer?)

From ethers.js/contracts/contract.js if (!signer) { return Promise.reject(new Error('missing signer')); }

On the mainnet using a contract to transfer the funds results in an empty promise with missing signer error {} (node:14972) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: missing signer

Here is my code:

provider : new ethers.providers.getDefaultProvider()
const contract = new ethers.Contract(this.address, contractABI, this.provider)
contract.transfer.call(fromAddress, toAddress, new ethers.utils.BigNumber(0))

Trying to do it with BNB, all addresses are valid.

I found ERC20 transfer method only have 2 input parameters, so it don’t need set the fromAddress.

contract.transfer(toAddress, ethers.utils.bigNumberify(0));
