my schema is like:-
{
key: 'triggers', required: true,
children: [
{ key: 'trigger_name' },
{ key: 'template_uuid' },
{ key: 'utm_source' },
{ key: 'utm_campaign' },
{ key: 'utm_medium' },
{ key: 'utm_content' },
{ key: 'utm_term' },
{ key: 'account_adapter_uuid' },
{ key: 'custom_url_params' ,children:[{key:"name"},{key:"value"}]},
],
},
giving error only one level of nested child is allowed
