Getting an error using the Structure field

Kirby 4 Question❓
1

I use the Structure field on multiple pages of different websites. Having added a new Structure field to a page, I’m getting an error I haven’t seen before and I can’t figure out what is wrong. (The same website already has two other Structures working perfectly.)

Everything works fine in the Panel but, for thoroughness, the blueprint setup is a follows…

fields:
  bulletin:
    label: Bulletin board
    type: structure
    columns:
      headline:
    fields:
      headline:
        type: text
      text:
        type: writer

I have checked my snippet’s PHP code against the working examples and they are exactly the same except for the field names. I cannot see where the issue is…

<?php $items = $page->bulletin()->toStructure(); $n = 0; foreach ($items as $item): $n++; ?>
<?php if ($item->headline()->isNotEmpty()): ?><h4><?= $item->headline() ?></h4><?php endif ?>
<?php if ($item->text()->isNotEmpty()): ?><?= $item->text() ?><?php endif ?>
<?php endforeach ?>

The error I am getting is as follows…

TypeError thrown with message "Kirby\Content\Content::__construct(): Argument #1 ($data) must be of type array, string given, called in C:\xampp\htdocs\projects\wendoverds\kirby\src\Cms\StructureObject.php on line 38"

Can anyone identify the problem? Thanks.

This error was reported in another thread, but only in the context of a structure field within a custom block and only for already existing structures. Could you please post what is stored in the structure in your content file?

I haven’t yet figured out why but this issue has resolved itself.
