Describe your Issue

Error: invalid hexlify value (argument="value", value="80000000000000000", code=INVALID_ARGUMENT, version=bytes/5.6.1)

    at eval (json-rpc-provider.js?8679:213:1)

I'm getting this error when using the provider from Magic auth to place a transaction (https://magic.link/docs/advanced/blockchains/ethereum/javascript)

Reproduction steps:

(async function() {
    const provider = new ethers.providers.JsonRpcProvider("http:/\/localhost:8545");
    const signer = provider.getSigner();
    await signer.sendTransaction({
        to: signer.getAddress(),
        value: "800"
    });
})();

This should be fixed in 5.6.5.

Let me know if there are any more problems.

Thanks! :)
