I'm trying to sign and broadcast a regtest P2PKH transaction.

previous transaction hex:

when I try to sendrawtransaction it throws a:

mandatory-script-verify-flag-failed (Script failed an OP_EQUALVERIFY operation)

I don't understand this error, but I've made a research about and found this: https://bitcoin.stackexchange.com/questions/84287/bitcoin-script-mandatory-script-verify-flag-failed-script-failed-an-op-equalver

As it suggested, I tried btcdeb:

I'm running out of ideas, that's why I need your help.

EDIT:

My error was to convert my dumpprivkey from base58 to hex using non-bitcoin tools. Some of non-bitcoin tools do not removes the first byte and the checksum, so the private key is altered.

The public key you are using, 039355776cdc3015a62d7a5d206003c5b4d754f2de3a2d9358114df3d0b1ec743b, has a HASH160 digest of b8e4fdb2bfa5a1cb796232ded6580c9ab52ffbb3.

Since the HASH160 you have provided in the script is different from the one evaluated in the stack, it is failing the equal verify operation.
