when using the fetch statement in JavaScript, like so:
fetch (url, data)
.then(response => response.json())
.then(data => {})
.catch ((error)=>{console.error ('Error: ',error)});
If an error occurs such as:
Error: SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data
Is there somehow to view the raw data that was received by the call and led to the parsing error, rather than just the error message?
For anyone on the lookout for a solution similar to mine, I discovered the solution over at Fetch API get raw value from Response
fetch(url)
.then(response => response.text())
.then((dataStr) => {
console.log (dataStr);
let data = JSON.parse(dataStr);
data...
Retrieve the content of the response as text and then proceed to convert text into JSON in a later step - consider outputting the text returned initially to identify any potential errors.
