How to send a private transaction using Quorum

Question

I'm trying to send a private transaction using Quorum geth, but eventually got an error :

Error: ether value is not supported for private transactions
    at web3.js:3143:20
    at web3.js:6347:15
    at web3.js:5081:36
    at <anonymous>:1:1

I notice that Quorum can't transfer balance privately, as this issuse mentioned

But even if I specify ether value to 0, the error still remain :

> eth.sendTransaction({
    from: eth.accounts[0],
    to: "0xca843569e3427144cead5e4d5999a3d0ccf92b8e", 
    privateFor:["QfeDAys9MPDs2XHExtc84jKGHxZg/aj52DTh0vtA3Xc="], 
    value: 0
})

Private txns in Quorum are designed to be executed over private contracts, we have many examples, but I'd recommend starting on this page to understand how its done: https://github.com/jpmorganchase/quorum-examples/tree/master/examples/7nodes#demonstrating-privacy.

And as you've noticed, no value transfers are allowed in private mode at all. If you need to track balances privately, please examine 5nodeRTGS example: https://github.com/bacen/quorum-examples/tree/master/examples/5nodesRTGS
