Fix JSON trailing comma

A trailing comma after the last element in a JSON object or array causes a parse error. JSON does not allow trailing commas.

Common causes

  • Extra comma after the last item in an object or array.
  • Copy-paste from JavaScript (which allows trailing commas).

How to fix

  • Remove the comma after the last element.
  • Use a JSON validator to locate the exact position.
