[Bug]: Can't add 2 UCO/token transfers to the same address ( libjs )

[herissondev]

Description

When transferring UCOs using libjs, it is possible to add multiple transfers for 2 different addresses: for example sending 20 UCOs to address A and 15 to address B.
However, sending 2 transfers to the same address resolves as an invalid transaction.

I don't know if that is an expected behaviour or not. If it is, I think it should be explicitly said in the doc.

Here is the code I used :

const archethic = require('archethic')
const endpoint = "https://mainnet.archethic.net"
const seed = "myseed"
const seed_address = archethic.deriveAddress(seed, 0)
console.log("seed_adress : " ,seed_address)
async function main() {
    let tx = archethic.newTransactionBuilder("transfer")

    const address1 = archethic.deriveAddress('receiver1', 0)
    // const address2 = archethic.deriveAddress('receiver2', 0)
    
    tx = tx.addUCOTransfer(address1, 1.03)
    // tx = tx.addUCOTransfer(address2, 1.99). (WORKS !)
    tx = tx.addUCOTransfer(address1, 1.99)

    tx = tx.build(seed, await archethic.getTransactionIndex(seed_address, endpoint))
    
    const originPrivateKey = archethic.getOriginKey()
    tx = tx.originSign(originPrivateKey)

    
    console.log(tx.toJSON())
    const resp = await archethic.sendTransaction(tx, endpoint) 
    console.log(resp)

}
main()
