You're trying to spend a 25.04826416 BTC output that was created by mining in May 2015, which was spent a few days after its creation: https://blockstream.info/tx/45fd1c838a56798fe027f61bdfdab83845399175a3b9cced397c5a38e669bb49?input:14

Even if you have the private key for the address that output used at the time, the coin can't be spent again.

I don't know what you're trying to do - but spending the same coin twice isn't allowed.

  • thanks for your feedback and checked on my behalf. First of all, that TxID was generated when I run the Blockhash in Console (Bitcoin Core), which is why I use that TxID to createrawtransaction in the first place. Well, I really have No Idea that it was created and spent on May 2015, maybe because of this, that my Bitcoin Core was still "running to connect" with peers it stated here that "Last Block Time: Fri May 8 00:29:33 2015 - I gues that explains why. How should I know what happen to this Txid in the past? But then, really thanks to you.

The transaction id you mentioned in the createrawtransaction command either has no vout:1 or it has been spent already.

I used vout:0from below transaction:


Example of one transaction that I created using createrawtransaction, signed using signrawtransactionwithkey and broadcast using sendrawtransaction

This was a transaction on testnet so I didn't care about fees. You can use fundrawtransaction for fees.
