Nextjs fetch received by different nestjs endpoint

I'm doing a simple fetch on an internal page (like a product page), using a slug (like 'my-product') in the body, and it stopped working properly.

By debuggin it with the help of postman, making the precise same request on Postman leads to a right behavior and response, which is server properly by the endpoint POST api/kondos/findBy , that looks like this:

On postman the request looks like this:

But the same request using fetch, on a server side page on my Nextjs app, is looking like this:

export async function getKondoBySlug(slug: string) {
try {
  const body = { slug };
  const response = await fetch(`${apiUrl}/kondo/findBy`, {
    method: "post",
    cache: "no-store",
    mode: "cors",
    headers: {
      //"Content-Type": "application/json",
      'Content-Type': 'application/x-www-form-urlencoded',
      'Accept': '*/*',
      'Accept-Encoding': 'gzip, deflate, br',
      'Connection': 'keep-alive'
    },
    body: JSON.stringify(body)
  });
  return await response.json();

} catch (error) {
  console.log('FETCH ERROR', error);
}

}

And this function it's being propely called on my page at: /src/app/(singles)/(default)/single/[[..slug]]/page.tsx , like this:

By debugging everything, I understand that the request is being wrongly received by the api endpoint GET api/kondos/findOne, that looks like this:

How come the same identical requests are received by different endpoints in the api ?

So, i figured out that the apiURL on my Nextjs was poiting to http instead of https. That solved the issue for me.
