I am getting an error when I try to read a response twice:
I need the response in a form of text assigned to a cosnt, e.g. (api_response.text()) and then I need to pass the api_response.json() to a function:

if (api_response_text == 'true') {
  const api_request = await fetch(url, {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify(item),
  }).then(async api_response => {
    const api_response_text = await api_response.text();
    if (api_response.ok) {
      if (onCompleted) {
        onCompleted(await api_response.json());
      }    
    } else {                
      console.log(api_response_text)
    }
  });
}

I tired with clone() like so:

const api_response_clone = await api_response.clone();

and:

console.log(api_response_clone.text());

but then I got [object Promise] as the response text, which is not what I need.

Any suggestions how to fix this?
