Fix component view exception must be of type array, false given

What is the purpose of $version here?

In this context $version is an array with the props recovered from the component.yml file.

I'm investigating this bug, I'll get back to you.

I made a patch that seems to fix this issue.

The issue was that some component.yml files might not have examples, which I use in $this->versions and $currentVersion. In that case I just needed to send an empty array to display the component without adding examples values in it.

Can you tell me if it's okay for you ?

Reviewed.

This did fix the Olivero Teaser. Obviously, nothing is shown, but there's no error.

I did try with UI Suite USWDS, and although the components provided by that theme also were blank, no errors were shown.

However, once that theme was enabled, I did get the following error in the Olivero Teaser component view:

The website encountered an unexpected error. Try again later.

Here's a one-liner to quickly get UI Suite USWDS running:

<code>
ddev composer require drupal/layout_options drupal/ui_styles drupal/ui_suite_uswds; ddev drush en layout_options ui_icons_patterns -y; ddev drush then ui_suite_uswds -y; ddev drush config:set system.theme default ui_suite_uswds -y;

I'm missing something in your dependencies here.

I could only install drupal/ui_suite_uswds:^3.0@alpha with a fresh D10 install.
Once this ok I had this issue : Unable to install modules layout_options, ui_icons_patterns due to missing modules ui_icons_patterns.

Can you provide all the dependencies needed to make this work please ?

Sorry, my previous comment wasn’t formatted correctly. Fixed. It includes composer command for the required modules.

I saw the installing lines and thank you for providing it. But I am sorry I am still having issues installing your suite of modules ...

After the ddev composer require drupal/layout_options drupal/ui_styles drupal/ui_suite_uswds; I have this issue :
Unable to install modules: module 'ui_icons_patterns'. Its dependency module 'ui_icons' is incompatible with this version of Drupal core.

I'm using minimal alpha version in composer requirements and I am with Drupal 10.3.11 as you said in you first comment. I also tried other stuff to make it work but ui_icons is still the issue.
