React Native fetch() not outputting body in console log - react-native

Question

I am using fetch() to get some data from an API. When testing in Postman the data is returned successfully as JSON. However, when testing from react native app on android I get a text/html response, not sure why. How can I view the body of the response from the text in console.log() to debug? When I do console.log(resp) I can not see the body.
const response = await fetch('https://web.com/api/usersignup', {
method: 'POST',
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json'
},
body: JSON.stringify(formData)
})
.then(resp => {
this.setState({spinner: false});
console.log(resp);// output in console is pasted under this code
return resp.text();
//return resp.json();
})
.then((responseJson) => {
console.log(responseJson);
})
.catch(error => {
this.setState({spinner: false});
Alert.alert('Error', error.message);
throw error;
});
Output I get in Metro Builder when using console.log(). Does not include body.
Response {
"_bodyBlob": Blob {
"_data": Object {
"blobId": "63acc7d8-bd8a-4dd7-b33b-f0e4f202f97e",
"offset": 0,
"size": 0,
},
},
"_bodyInit": Blob {
"_data": Object {
"blobId": "63acc7d8-bd8a-4dd7-b33b-f0e4f202f97e",
"offset": 0,
"size": 0,
},
},

},
},
"ok": true,

"url": "https://web.com/api/usersignup",
}

You cannot print the body until the promise of first then is finished.
I made an example with your code: https://snack.expo.io/#egizas/fetch-print-body
const response = await fetch('https://jsonplaceholder.typicode.com/todos/1', {
method: 'GET',
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json'
},
//body: JSON.stringify(formData)
})
.then(resp => {
console.log('Printing out not json');
console.log(resp);
return resp.json();
})
.then((responseJson) => {
console.log('Printing out json');
console.log(responseJson);
})
.catch(error => {
this.setState({spinner: false});
Alert.alert('Error', error.message);
throw error;
});
Just replace the endpoint and provide correct header.
