Maybe I need to ask another question. If I implement $form_state->setRebuild(TRUE) via a submit form element, I am not sure how to get the altered/active field value, not the [#default_value].

See Examples, when you set $nojs in the ajax examples you get dynamic forms rebuilding without #ajax: cgit.drupalcode.org/examples/tree/ajax_example/src/Form

To avoid the error use isset(). For dynamic forms in general, try to not submit and save the values until the end. Rebuild the form instead, then check in buildForm() the value of field_number in $form_state and build the dynamic form elements accordingly.

The error comes from '#default_value' => $config->get('field')[$i]. So if you have 1 field and add 100, you get 100 notices of undefined offset. Not sure how to get an un-submitted form field value into $form_state as form fields don't have any type of '#onblur'or anything as far as I know. Hoping to add 100+/- fields in one click.
