How to avoid thymeleaf template might not exist when calling a method on the controller using Ajax? - ajax

Question

I have a button on my html:
<button id="btnSave"
type="button"
name="formAction"
onclick="saveAddWorkItem();"
value="save"
class="btn btn-default">Save Ajax</button>
And on my javascript I have this:
function saveAddWorkItem(){
const params = $("form").serialize();
$.ajax({
type: "POST",
url: "/nonInstructionalWorkload/saveAjax",
data: params,
success: function (data) {
alert("Saved Work Item");
}
});
}
It's calling properly the method on the controller:
def saveAjax(){
println("Save Ajax")
println("Params Save Ajax: " + params)
}
But my problem is, once it executes the controller I was expecting it to go back to the "Saved work item" message on the js side.
I'm expecting to try and save the item, and if there is any validator error, etc it should go back to the js with it's messages, fields with error, etc so we could handle it and display the message to the user.
But instead I'm getting this error:

View: /error
There is no page saveAjax on my templates. And I don't need one, just need it to go back to the js function.
I can't see what I'm doing wrong here.

By default the Grails convention is to render a view named /controller/action. If you'd like to override this you could respond with JSON, or use a Gson View, or respond just with a status code.
See the render docs for more options depending on your usecase: https://docs.grails.org/latest/ref/Controllers/render.html
