I have placed the correct Developer ID certificates.

Have any of you successfully overcome these two problems I am facing to create a build of my electron app for the macOS store? I have included the correct apple certificate and entitlement properties but still electron is not detecting these things in the build process.

Errors:

ERROR ITMS-90237: "The product archive package's signature is invalid. Ensure that it is signed with your "3rd Party Mac Developer Installer" certificate."

ERROR ITMS-90296: "App sandbox not enabled. The following executables must include the "com.apple.security.app-sandbox" entitlement with a Boolean value of true in the entitlements property list
