SseClosestFormNotFound

No closest form could be found in the DOM. When setting the contentType option to form, the element must have a wrapping form, otherwise a selector must be provided to a form that exists in the DOM.

Example using a wrapping form:

1<form>
2    <button data-on-click={ "@" + action + "('/endpoint', {contentType: 'form'})" }></button>
3</form>

Example using a selector:

1<button data-on-click={ "@" + action + "('/endpoint', {contentType: 'form', selector: '#myform'})" }></button>

See the docs for the @get() action.
