Notice you’re dealing with a Response object. You need to basically read the response stream with Response.json() or Response.text() (or via other methods) in order to see your data. Otherwise your response body will always appear as a locked readable stream. For example:
fetch('https://api.ipify.org?format=json')
.then(response=>response.json())
.then(data=>{ console.log(data); })
If this gives you unexpected results, you may want to inspect your response with Postman.
