Status: Active » Closed (cannot reproduce)

I tried to reproduce the steps by installing a clean D9.4.x-dev and doing

1. create a view display (of the feed type)
2. select field as the style setting
3. add fields to the field portion of the view config
4. click on "save"

I don't see any error in the log or the JS console.

Looking at line 323 of FieldPluginBase.php I can see why this error might occur:
$elements += \Drupal::config('views.settings')->get('field_rewrite_elements');

If the field_rewrite_elements config item does not return an array. That should always be the case, unless an invalid config is somehow loaded.

If you can still reproduce this on a clean D9 install please feel free to reopen this issue.
