I'm currently developing a page for an upcoming unicycling competition where teams from all over the country attend and the entry is completely free for everyone.



I tried to support my SEO by inserting structured data as JSON-LD, but the google search console and the structured data testing tool complain about not having offers and a performer. Those are "Warnings".



Is it save to ignore "Warnings" or should I fill that data in somehow and if yes how?

My current data (real data replaced):

    {
      "@context": "https://schema.org",
      "@type": "SportsEvent",
      "name": "Competition",
      "description": "Some Fine Descriptiont",
      "image": "https://url.de/image.jpg",
      "startDate": "startDate",
      "endDate": "EndDate",
      "location": {
        "@type": "Place",
        "name": "Arena",
        "address": {
          "@type": "PostalAddress",
          "streetAddress": "Street",
          "addressLocality": "City", 
          "postalCode": "12345",
          "addressCountry": "DE"
        }
      }
    }
