an error occurs when I try to make a transaction

[sasdecompte]

Hello
why i have this error -> "ERROR [2023-12-28T00:42:35.518Z] Failed to add one transaction to pool." when I try to make transaction ?
Is there an error in my new transaction object ? ->

const transaction = new Transaction("041ce8d242440c5dc46868eb73abc913c9875ebebcf3152070ae146655bfdeebf082ba329fc4a565040873a2cfe56f46dd045153654b48fb1ee794bec04d2105fd", "100", "1", {}, 10);

Transaction.sign(transaction, ec.keyFromPrivate("84f054b3f3183be5dab51d60d34cf6e0783ac9db6671ade83dfbda0f1cc88860"));

axios
.post("http://localhost:5001/sendTransaction", {
params: { transaction: Transaction.serialize(transaction)},
})
.then((response) => {console.log(Response, response.data);})
.catch((error) => {console.error(2ndError, error.response.data);});

There could be several reasons to why this would happen:

1. Insufficient balance: Initially, the whole total supply is minted to one account only, so I guess the above failed because you have no coin in your account. To mint the supply into your account, change FIRST_ACCOUNT in src/config.json to your address.
2. Incorrect nonce: I see you have your nonce set to 10. But if you have not made any transaction before then it should have been 1. To programmatically get the nonce you can also use the get_nonce rpc method.
3. Incorrect address: In the past, addresses in JeChain can be whatever, but now it must have the length of 32 bytes (64 characters) and is a valid hex string, more precisely, addresses in JeChain are SHA256 hashes of public keys, you just need to get the SHA256 hash of the address in your code and you are good.

If you have any further problem, feel free to ask!

First of all thank you for your reply,
I generated two addresses with keygen.js -> /src/utils/keygen.js

Address n°1, mining the blocks ->
Address : "60aafa56e838661b90a147d2fe13149ef8e3513a44530c5a7fa37301985ed349"
Public key : "04641218a10e698a21ac9eba4e3b29a30a9dd07bbb8d98136b576bbc19fe6f3187195936550cf4ce8d898b9e9687345ab62351df350f17d777e94e9cbaa9092f87"
Private key: "84f054b3f3183be5dab51d60d34cf6e0783ac9db6671ade83dfbda0f1cc88860"

Address n°2, do nothing
Address : "535f3a402d563320e153d902bcfe178572128033adc7d293760d4dd78c5c53d1"
Public key : "041ce8d242440c5dc46868eb73abc913c9875ebebcf3152070ae146655bfdeebf082ba329fc4a565040873a2cfe56f46dd045153654b48fb1ee794bec04d2105fd"
Private key: "a497a4a79ca256f5855e4b07d155c2a5f3c44d5d68700e58f7c6fc097efc34e1"

When i check the balance of each account i have these responses :

FIRST_ACCOUNT ->
Response { success: true, payload: { balance: '100000000202977000000000000' } }

Address n°1 ->
Response { success: true, payload: { balance: '24357240000000000000' } }

Address n°2 ->
2ndError { success: false, payload: null, error: { message: 'Invalid request.' }}
(this is normal, this address is empty)

When i get_nonce i have this response ->
Response { success: true, payload: { nonce: 0 } }

I'm trying to send 100 from Address n°1 to Address n°2,
and when I write the transaction, i put this :

const transaction = new Transaction("041ce8d242440c5dc46868eb73abc913c9875ebebcf3152070ae146655bfdeebf082ba329fc4a565040873a2cfe56f46dd045153654b48fb1ee794bec04d2105fd", "100", "1",{}, 0);
Transaction.sign(transaction, ec.keyFromPrivate("84f054b3f3183be5dab51d60d34cf6e0783ac9db6671ade83dfbda0f1cc88860"));

axios
.post("http://localhost:5001/sendTransaction", {
params: { transaction: Transaction.serialize(transaction)},
})
.then((response) => {console.log(Response, response.data);})
.catch((error) => {console.error(2ndError, error.response.data);}); 

in the terminal i have this response ->
Response { success: true, payload: { message: 'tx received.' } }

But after i have this response ->
LOG [2024-01-05T01:04:48.673Z] Sent one transaction.
ERROR [2024-01-05T01:04:48.743Z] Failed to add one transaction to pool.

when i tried with "nonce : 1" or changed FIRST_ACCOUNT with Address n°1, I have the same error.

So do you have any idea where the error could come from?
In advance, thank you for your answer

Oh it's the point 3 that I have made, addresses are not public keys, they are SHA256 hashes of public keys, so I think changing 041ce8d242440c5dc46868eb73abc913c9875ebebcf3152070ae146655bfdeebf082ba329fc4a565040873a2cfe56f46dd045153654b48fb1ee794bec04d2105fd to 535f3a402d563320e153d902bcfe178572128033adc7d293760d4dd78c5c53d1 would be okay.

sorry... I didn't understand this point, thanks for your patience. Now it works. Great!
