Contract that uses InfuraProvider sends a transaction instead of calling the view contract function

See original GitHub issue

As stated, deploy a contract with a view function. Get the provider like

const provider = new ethers.providers.InfuraProvider('rinkeby', PROJECT_ID);
const contract = new ethers.Contract(CONTRACT_ADDRESS, ABI, provider); 

await contract.getListOfThingsForExample();

Then it throws this error

{
  ...
  reason: 'sending a transaction require a signer',
  code: 'UNSUPPORTED_OPERATION',
  operation: 'sendTransaction' 
}

Since this is a query, it shouldn’t require a signer. Which means contract is trying to send a transaction

Seems like I was using v4.0 beta. Installed 5.0.32 and it’s working now. Thanks!

Can you make sure your ABI correctly specifies that getListOfThingsExample is correctly marked as view or peer?
