I'm newbie with bitcoin, i'm trying to generate a rawtransaction but bitcoin-cli sendrawtransaction return me an error code -25.
The transaction is
{
"locktime": 0,
"version": 1,
"vin": [
{
"sequence": 4294967295,
"scriptSig": {
"hex": "48304502204912c3f006284a9d0b57ded3fc8f04f72e2a48000f28967e0069bda6a9d8bac6022100e7af707986ff5b52e5d5868726156eded2ef29ccda1a8ad83f98d71597dcdce3012102d7c641bc6e04d3717416356e1b42fb5c5be6780f8c819715789efc6dafdf0539",

}
],

}
