When we do this (see below) in adjustCertInformation function, we are saying we always have all the sections (e.g "Extended Key Usages") but is not always like that.

certItems.push({
    sectionTitle: "Extended Key Usages",
    sectionItems: [createEntryItem("Purposes", cert.ext.eKeyUsages.purposes)],
    Critical: cert.ext.eKeyUsages.critical || false,
  });

I was testing with the URL defined below and I got cert.ext.eKeyUsages is undefined.
