When run cert-issuer -c /etc/cert-issuer/conf.ini , I got this error:

How to resolve this?

I can't really help there, I don't have enough details. It could be something with your issuing address? It could be your private key file too. I have found that it prefers the WIF format of the key.

I use bitcoin-cli getnewaddress to get the issuing address. How do I get that in the WIF format?

hm it looks like it might already be what you did from the readme:

https://chainquery.com/bitcoin-cli/dumpprivkey

Can you make sure that this private key looks valid? This tool might help you: https://learnmeabitcoin.com/technical/wif

I have made sure the key is valid. Here're more details of the error:

Also I had to comment the rpcport=8332 in the bitcoin.conf file because when I ran bitcoind -regtest -daemon it said:

Error: Config setting for -rpcport only applied on regtest network when in [regtest] section.

So I commented bitcoind in /etc/cert-issuer/conf.ini .

issuing_address=bcrt1qdx5yve0nqfmlcjn42uwngyavynvrcz46wg83dh

verification_method=did:ion:EiA_Z6LQILbB2zj_eVrqfQ2xDm4HNqeJUw5Kj2Z7bFOOeQ

chain=bitcoin_regtest

usb_name=/etc/cert-issuer/
key_file=pk_issuer.txt

unsigned_certificates_dir=/etc/cert-issuer/data/unsigned_certificates
blockchain_certificates_dir=/etc/cert-issuer/data/blockchain_certificates
work_dir=/etc/cert-issuer/work

no_safe_mode

#bitcoind

Then run cert-issuer -c /etc/cert-issuer/conf.ini and got a different error:

I don't know about this error. Can you try with bitcoin testnet instead? Make sure your address is valid for that network.
