Why CSR extensions are not being transferred to the certificate?

Due to this, the extensions which we added in our CSR were not transferred by default to the certificate. So these extensions must be added to the certificate explicitly.
Why is my CSR for San empty?
So our CSR contains all the IP Address and DNS value which we provided while generating the CSR for SAN. We get an empty output. The SAN Extensions are missing from our certificate. This is an expected behaviour.
What is the issuer field on a self-signed certificate?
