Showing an error while calling solidity contract, which is deployed already in ropsten-infura. I'm using web3(@0.19.1) for calling contract.
Anybody faced the same issue?

See Question&Answers more detail:osI'm guessing that you're connected directly to Infura, which doesn't support eth_sendTransaction
. (For it to support that, it would need to know your private key, but it's a shared public node.)
You need to either sign the transaction yourself and then send via eth_sendRawTransaction
or use a provider that can hold private keys like MetaMask in the browser.
