Transacation

in public test net when TransactionBuilder finalize in Signature.js，when nonce = 1,it will occur Error
nonce = 0;
e = _bigi2.default.fromBuffer(buf_sha256);
while (true) {
ecsignature = (0, _ecdsa.sign)(secp256k1, buf_sha256, private_key.d, nonce++); //here
der = ecsignature.toDER();
lenR = der[3];
lenS = der[5 + lenR];
if (lenR === 32 && lenS === 32) {
i = (0, _ecdsa.calcPubKeyRecoveryParam)(secp256k1, e, ecsignature, private_key.toPublicKey().Q);
i += 4; // compressed
i += 27; // compact // 24 or 27 :( forcing odd-y 2nd key candidate)
break;
}
if (nonce % 10 === 0 && process.env.ENVIRONMENT === 'DEV') {
console.log("WARN: " + nonce + " attempts to find canonical signature");
}
}

in ecdsa.js will always occur error

function deterministicGenerateK(curve, hash, d, checkSig, nonce) {

(0, _enforce_types2.default)('Buffer', hash);
(0, _enforce_types2.default)(_bigi2.default, d);

if (nonce) {
    hash = (0, _hash.sha256)(Buffer.concat([hash, Buffer.from(nonce)])); **//here**
}

// sanity check
_assert2.default.equal(hash.length, 32, 'Hash must be 256 bit');

var x = d.toBuffer(32);
var k = Buffer.alloc(32);
var v = Buffer.alloc(32);

some account will occur,some account not, ex: public-account-1 will
but i create an account:
name: in-oawwoaww6
private key: 5KQ4GsMP4N6NwtaHqBYvmAq5PwUQPsJB299xk5e6n5j36v6kreo
public key: DCT7UDjcPUGToUNUmUFG4svw3KxSHvDUeYMrbZUF5HcqwyVvBSk3J
will not occur
