Suggested Fixes

  • Check if the word null is spelled correctly.
  • Ensure that null is not surrounded by quotation marks.
  • If the null value is not intended to be used as the JSON null value, enclose it in double quotation marks.
  • If the value is quoted, make sure that there is no missing starting/ending quotation mark.
  • If the value is quoted, make sure that there are no extra trailing/leading quotation marks around the value.
  • Make sure that the property value is properly escaped.
  • If there is any extra content before the actual JSON content, remove that.
