I’ve created a uncooked transaction, and I get this error when I attempt to ship it with sendrawtransaction to my native bitcoin regtest:
{

"code": -26,
"message": "mandatory-script-verify-flag-failed (Signature have to be zero for failed CHECK(MULTI)SIG operation)"
},
"id": "1",

}
That is the transaction from which I wish to spend:

I carried out the next steps:
- Create the uncooked transaction. That is the uncooked transaction:

- Add 01000000 on the of the transaction. That is the hex of the transaction earlier than signing:
0100000001c220d5c6404a03347826f8375d3ef779c2e9d9d559050c3579eca2ddbbf6d495000000001976a91459fe1a9f9f0a5af33396c59990f064be1ca5127488acffffffff020065cd1d000000001976a9141af72e49ec135151f1421c185b6cb1ce836576c388acc0269dd0000000001976a91459fe1a9f9f0a5af33396c59990f064be1ca5127488ac0000000001000000
- Double SHA256 the uncooked transaction from step 2. That is the hash:
0b5a635ff615175cb114f051ea89e3f90e373dc059fc5ec8059ceeea4b42099f
- Signal the transaction. To signal the transaction I’ve to make use of an endpoint of an HSM. I’ve to ship the general public key and the hex of the transaction and it returns the signature. The returned signature seems to be like this:
3044022052fe83beb097408e84d138bc4f723507f626b0f07019385df2103ebfc559a67a02206b5281554dfd80f1a29a0257d9cdfe07a7f7684d52c6ef875678ea3e3d289451
That is the general public key:
3056301006072a8648ce3d020106052b8104000a034200049665be7c887cc801b1f6c5bb189434aa0a0635cd23d3b62832ffe3be70e9a3af64b03bb1217ee29ff2a0d5a88ff433c531cef6ba29f080e047f24f7e612bd93b
That is the signed transaction:

- Ship the signed transaction with rpc
sendrawtransaction:

sendrawtransaction returns the next error:

"code": -26,
"message": "mandatory-script-verify-flag-failed (Signature have to be zero for failed CHECK(MULTI)SIG operation)"
},

What does this error imply? What am I doing improper?
