Description

React Native SDK currently supports linked exceptions using cause but doesn't support AggregateError.

Notes

• Implementing this might likely change grouping so it should be done in a major version.

Works

{
    "message": "Third",
    "cause": {
        "message": "Second",
        "cause": {
            "message": "First",
        }
    }   
}

Not implemented at the moment

{
    "message": "Third",
    "errors": [
        {
            "message": "First",
        },
        {
            "message": "Second",
        },
    ]
}
