missing provider when calling signer.sendTransaction

[ihorbond]

Hey guys I'm using ethers with metamask like this

const provider = new ethers.providers.Web3Provider(window.ethereum)
const signer = await provider.getSigner() // no arg so using accounts[0]

console.log(provider, signer) // all good 

const tx = { ... } 

await signer.sendTransaction(tx) 

this results in
missing provider (operation="sendTransaction", code=UNSUPPORTED_OPERATION, version=abstract-signer/5.5.0)

what am I doing wrong ? I tried re-connecting the provider by calling singer.connect(provider) but it returns
cannot alter JSON-RPC Signer connection (operation="connect", code=UNSUPPORTED_OPERATION, version=providers/5.5.0)

@ihorbond, I just tried reproducing using the code you provided, it opens the metamask box for me (I don't get an error). Are you using something other than metamask?

provider = new ethers.providers.Web3Provider(window.ethereum)
signer = await provider.getSigner() // no arg so using accounts[0]

console.log(provider, signer) // all good

tx = {to: ethers.constants.AddressZero, data: '0x1234' } 
await signer.sendTransaction(tx)

Thanks. I ended up signing contract and calling methods on it directly. Not sure what I was missing here, maybe I was formatting my tx object wrong
