Come together with the global Drupal community in Rotterdam, 28 Sept – 1 Oct 2026. Sessions, contribution, connection, and Early Bird savings until 8 June.Problem/Motivation
When using a view that has block_content as entity type id, the following warning is generated.
Warning: Undefined array key "#theme" in Drupal\swiper_formatter\Plugin\views\style\SwiperFormatterStyle->render() (line 234 of modules/contrib/swiper_formatter/src/Plugin/views/style/SwiperFormatterStyle.php).
Steps to reproduce
1. Navigate to /admin/structure/block-content, and create a Block Type if you don't have any.
2. Create a few block contents.
3. Create a view that shows "Content Block".
4. Apply the swiper formatter style plugin.
5. If the view is a block, place it somewhere. I used a block in layout builder.
6. Navigate to the page and observe the warning.
Proposed resolution
When debugging this, I noticed that the block content had the key '#entity_type'. So, my proposition is to add an extra case in the if statement that checks for the entity to have it work for this case. I compared with nodes, and indeed nodes don't have it, but block_content has it.

chrisolofI just ran into this bug while attempting to display ECK entities in a views block using the swiper formatter views plugin. The changes in MR 2 fix the issue for me. Thanks @bbu23!
Attached is an immutable patch snapshot of MR 2, as it stands today.

nk_ commentedThank you all! It was finally committed in the new release, the last one supporting Drupal 8.8 and 9. A brand new branch 2.0.x with quite some new features is there and recommended for a future use.

bbu23It seems that the tag 1.0.7 was created prior to the commit that fixes this in 1.0.x.
Not sure if you're aware of this, so the change + another one are not included in 1.0.7
Comment #10
bbu23Temporary solution for 1.0.7 is applying the commit patch (if anyone needs it): https://git.drupalcode.org/project/swiper_formatter/-/commit/59bda303dea...
