Are you building a JSON request using String manipulation?
If you are, then you may need to escape any braces that aren't being used to insert placeholder content. You do this by adding an extra opening brace. For example...
{{
"test" : {1}
}
Ideally, you should be using an Export Mapping and JSON Structure as this handles escaping automatically.
I hope this helps.
Please use online Json Viewer. https://jsonviewer.stack.hu/
Brace should be followed by number of digits or another brace.
Can you share the sample JSON you are using to validate.
Are you using below format?:
[ { "idGear": "1", "name": "lala", "year": 2000, "price": 15.0 }, { "idGear": "2", "name": "lala2", "year": 2000, "price": 125.0 }]
