Unable to get the cert

[iamantil]

First generate a private key:
openssl genrsa -out ./private.key 2048

Then use hvclient to create a CSR:
./hvclient -privatekey ./private.key --commonname example.com -csrout csr.pem > csr.pem

Then we can look at the CSR, (this is optional)
openssl req -in csr.pem -text

We can then issue a cert
hvclient -commonname Demo_cert -csr csr.pem | openssl x509 -req -extfile <(printf "subjectAltName=DNS:pki.atlasqa.co.uk") -text -signkey test.key -out certificate.crt

Got below error:
hvclient: couldn't obtain certificate: 422: san.dns_names: has to have between 1 and 2 items

I think this is an error with the input, the error is saying you need to put a SAN (dnsnaems) in the request i.e.
./hvclient --commonname example.com -dnsnames example.com -csr csr.pem
