N1QL resultset contains invalid JSON

Seen in a response:
},\n\n ],\n "status": "timeout",\n "metrics":

{\n "elapsedTime": "1m15.540084496s",\n "executionTime": "1m15.540053887s",\n "resultCount": 60085,\n "resultSize": 79286006\n }

\n}\n

Note the },\n\n ] (first text in the beginning) – this is invalid JSON as the final item of an array should not have a trailing comma.

Unfortunately I cannot obtain more context, and the parser is streaming, so the remaining text is basically what the parser was not able to consume.
