 * Hi there, our website has recently started throwing back “{code: ‘invalid_json’,
   message: ‘The response is not a valid JSON response.’}” upon successful submission.
 * Do you have any idea why?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fgetting-response-code-invalid_json%2F%3Foutput_format%3Dmd&locale=en_US)

 * It seems that the following message is added to REST API responses and that is
   breaking the JSON syntax.
 * > ERROR: Column ‘FinalScore’ cannot be null
 * Do you have any idea what it is?

 * Hi there,
 * That’s amazing thanks, that’s allowed me to debug and fix the issue.
 * Could you please let me know how you can read the REST API responses?
 *  I could only see:
   `{code: ‘invalid_json’, message: ‘The response is not a valid
   JSON response.’}`In the browser console log which isn’t that helpful…
 * Many thanks,
   Karl

 * I guess it’s up to the configuration of the browser console. Try turning on output
   for XHR requests.
