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"
    }
  }
}
