Try something like:
[
{
"name": "Some element. The name field is necessary",
"url": "http://www.example.com",
"somethirdfield": "a"
},
{
"name": "Another element",
"url": "http://www.example1.com",
"somethirdfield": "b"
},
{
"name": "Another element",
"url": "http://www.example2.com",
"isReferenceValue": true,
"somethirdfield": "c"
}
]
Your old input was: ${value}`;
setValue(substituteText);
}
};
