Post FromBody Always Null

If the model is null, check:

1) Where the data is sent: body, form? and based on that add the decorator to the action. For ex:

[HttpPost]
public JsonResult SaveX([FromBody]MyVM vm) { ... }

2) Check ModelState: if it's invalid the vm will not be bound so it will be null.

if (ModelState.IsValid) { ... }

You get always null because you need to encapsulate all your post variables inside only one object. Like this:

public class MyPostModel {
    public List<string> userSocs {get; set;}
    public int collegeId {get; set;}
}

and then

public async Task<IActionResult> GetStudentResults([FromBody] MyPostModel postModel)
