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",
		},
	]
}
