I managed to add a test certificate to bitcoin regtest by following the instructions in the cert-issuer README.md. However when I attempt to do the same process on the bitcoin testnet, I get the following error when attempting to issue with cert-issuer -c /etc/cert-issuer/conf.ini.

Hey @07smithlewis, I am sorry this is not the project I know most.

have you looked at this similar issue? #61

Otherwise the error is likely being thrown from here:

cert-issuer/cert_issuer/blockchain_handlers/bitcoin/signer.py

Line 27 in c3c7233

def sign_transaction(self, wif, transaction_to_sign):
, so what I would do is try and debug starting from there, you might find some insight.
