However you can see it's coming in the POST as NULL.

In Chrome -> Dev tools -> Network tab. The Form Data is

An array is posted but the action expects a single object.

Also for model binding from the body of the request you can use [FromBody] attribute

[HttpPost]
public IActionResult InsertMasterTemplate([FromBody]headingstree[] tree) {
    //...
}

Reference Model Binding in ASP.NET Core

ensuring to include:

contentType: "application/json; charset=utf-8",`

in the AJAX method,
