I have a website running on nextjs v12 & the content is fetched through strapi cms, as strapi cms used to go down due to high load which resulted in website downtime. So in order to solve this problem, I came up with the solution of serving static data through api (i'm using lambda function + s3 bucket to store static data for individual page) whenever strapi goes down, so that website keeps on running no matter if strapi is down. I have also added slack alerts when strapi goes down which is triggered in the lambda function itself. Below is the code samples for understanding :-

NextJs website :- pages/index.js

export default ({ data }) => {
  return <Home data={data} />
}

export async function getServerSideProps(ctx) {
  let homePageData;
  homePageData = await getHomePageDataFromStrapi(); // fetches data using graphql from strapi
  if (homePageData.notFound) {
    // strapi is down, get data from s3 instead
    homePageData = await getHomePageDataFromLambda(ctx.req.headers.host);
    if (!homePageData) {
      return { notFound: true };
    }
  }
  return {props: { data: homePageData }}
}

call to lambda function :-

function getHomePageDataFromLambda(host){
  const res = await fetch('', {method:'POST',headers:{origin: host},body:JSON.stringify({filePath:'/homePageData.json'})})
  const data = await res.json()
  if (data.data) return data.data;
  return null;
}

lambda function :- responsible for returning static data which is stored in a file in s3 and i maintain a file which consist of down-pages path & send slack alert accordingly.

The issue is that even if strapi is not down i.e. notFound: false, the lambda function gets called & i get slack alert (this only happens sometimes), so i'm confused why this is happening, is this could be a nextjs behvaiour? like it runs server side like a bot or a crawler & i don't really know why? Does someone have an explanation?
