What causes a 'JSON parse error: unexpected token' when the error message includes 'love island usa'?

This error typically means the string you're trying to parse as JSON is not valid JSON. The inclusion of 'love island usa' in the error message suggests that this string *is* part of the invalid JSON data itself, likely appearing where a valid JSON token (like a colon, comma, bracket, or string value) is expected. It's not the cause, but a piece of the problematic data. Common causes include incomplete JSON, extra commas, unescaped characters, or simply text that isn't JSON at all. The 'love island usa' part is just what the parser encountered at the point of failure.
