Unexpected token W in JSON at position 0

Comment

Unexpected token W in JSON at position 0

It's because a simple string (plain text) is returned as the response. The text is not a valid JSON. So when you try to do res.json(), it calls JSON.parse(data). Try and do it with the string you provided, and you will get the same error.

use res.text() instead of res.json()

  const jsonObject = JSON.parse(jsonString);
  console.log(jsonObject);
} catch (error) {

    // Handle the syntax error
    console.log("Invalid JSON object. Please check the syntax.");

unexpected token c in json at position 0

Comment

// The message you see is that your JSON response is not formatted correctly

// GOOD JSON:

{ "name":"John", "age":31, "city":"New York" }
BAD JSON

    { 'name': 'john' }
    { name: "john" }

// OR

{ 'name' = 'john' }

// In your case, the JSON begins with character C keep in mind that a valid Javascript object could be invalid JSON form

syntaxerror: unexpected token u in json at position 0 at json.parse

Comment

 "SyntaxError: Unexpected token u in JSON at position 0" usually indicates that there is a problem with the JSON data being parsed.

The "u" token is not a valid JSON token, so it's likely that the JSON data is corrupted or not properly formatted.

Here are some solutions:

Check the JSON data to ensure it's properly formatted and there are no unnecessary characters at the beginning of the string.

Make sure the data being passed to JSON.parse() is a string, as JSON.parse() expects a string argument.

If you're reading the JSON data from a file or network request, ensure that the encoding is correct and there are no byte order marks (BOM) or other invisible characters causing issues.
