JSON errors, answered on the page
Paste the text the error came from. The page says what each parser meant, where the break is, and fixes it with the fix named on its line.

Trailing comma in JSON
A comma after the last value of an object or an array. JavaScript, JSON5 and most config dialects allow it; JSON does not, and every parser stops at the bracket after it.

Expecting ‘,’ delimiter
A comma is missing between two values — after a property, or between two items of an array. Python calls it a delimiter; V8 says which two characters it expected; both point one token past the break.

Unexpected end of JSON input
The text ends before the document does — cut by a buffer, a log line limit, or a copy that missed the last lines. Every parser reports the end of the text; the fix closes what was left open and says how many.
