Trailing content after the JSON value

What it means

A JSON document contains exactly one top-level value. If more tokens follow — often two objects pasted back to back, or newline-delimited JSON (NDJSON) — the parser reports the leftover content.

Example

{ "id": 1 }{ "id": 2 }

[{ "id": 1 }, { "id": 2 }]

How to fix it

Wrap multiple values in an array, or split them into separate documents.

Validate your JSON to see this and every other issue highlighted in one pass.
