Signing electron-builder generated package on windows fails when using self signed certificate

I have js project that ive packaged with electron-builder. I want to sign windows package with self signed certificate. My build machine is Windows Server 2019 64 bit. Node version 12.18.2 I use electron-builder 22.7.0.

Ive generated pfx file on the different windows machine using following power shell commands

New-SelfSignedCertificate -DnsName www.github.com -CertStoreLocation cert:\LocalMachine\My -type CodeSigning
$pw = ConvertTo-SecureString -String sillypassword -Force –AsPlainText
Export-PfxCertificate -cert cert:\localMachine\my\SOMELONGNUMBERFROMFIRST COMMAND -FilePath $env:USERPROFILE\Desktop\Cert.pfx -Password $pw

Ive exported CSC_LINK and CSC_KEY_PASSWORD with proper values and im running electron-builder -p always --win to publish the package.

And i got following error

Exit code: 1.

I can sign it on my test machine that ive created specifically to test this behaviour, but it fails in Travis. How can i debug this situation to know what im doing wrong. Thanks

For self-signed certificate, you'll probably need to first check if this cert was imported to your cert store. Then verify if the subject name was set properly. electron-builder (v22.6.0 - v22.8.1) has a bug signing windows store apps: https://github.com/electron-userland/electron-builder/issues/4931, but it may or may not have any relation to your windows .exe signing.
