CSP issues are less directly related to the 'unexpected token' error itself, but misconfigured CSP can prevent your Next.js application from correctly fetching resources, which could indirectly lead to errors if a fallback mechanism returns HTML instead of JSON. Review your CSP headers to ensure they allow requests to your API endpoints.
