I’m trying to run cert-issuer for bitcoin testnet on my local system. I have done all the installation correctly and created an issuer_address and add the balance to it. Now, when I try to run cert-issuer -c conf.ini to issue certificate I got an error as : pycoin.encoding.EncodingError: bad character 123 in string
