I've developed a chrome extension. I am not able to capture the API response but I can see the response in the network console.

Below is my code

async function generateUniqueId(){
   let uniqueId = Date.now();
   let formData = new FormData();
   formData.append("userId",uniqueId);
   fetch('http://localhost:3000/v1/registerUser',{
    method:'POST',
    body:formData
     }).then((response)=>{
          console.log(response);
          chrome.storage.local.set({'userId': uniqueId}, function() {
            console.log('Value is set to ' + Date.now());
          });                      
      }).catch((error)=>{console.log(error)});
}

In the below image you can see the response in the Network tab but when I print it in the console it's showing empty. Can someone please help?
