Hi, I have been using a Developer ID Installer Certificate to sign my installer packages since a long time now. Recently, the sign command started giving me error, Error - Certificate is expired or not yet valid. Please check certificate validity. The certificate itself is valid till 2025, so I am confused on the issue. To get a clearer understanding, I created a new certificate by following instructions in the link, https://developer.apple.com/help/account/create-certificates/create-developer-id-certificates However, when I try to use this to sign my installer package, I get the following error, Unable to build a valid certificate chain. Please make sure that all certificates are included in the certificate file. I am using ZXPSignCmd to sign the installers. Hoping for guidance to a quick resolution.
