Update from 10.2.7 to 10.3.0 claro theme error InvalidArgumentException

switch to other theme, not claro, the problem was avoided, not resolved.

I know this isn't specific to the Claro theme, but I applied this change from the Gin theme: https://git.drupalcode.org/project/gin/-/merge_requests/416/diffs

And it fixed this error. Hope that helps!

I think this error went away for me after running database updates and clearing caches.

Thank you so much! The change works!

This issue persists in version 10.3.0. Updating the database and clearing the cache didn't help.

Problem verified in local version. I didn't update the production version so as not to run the risk of having the site down until the issue is fixed.

There isn’t code to review.

I performed the update test on two projects: an empty website and an older one, with the local version of a website that is in production.

Actually, in the version with an empty database, just do the update, run "update.php" and clear the cache. The website will continue to operate.

However, I note that in more complex versions, these measures did not work. After the update, it is not possible to access any page on the website, as it is offline. This should not happen, as not everyone knows how to restore a website.

However, on the older site, it is still possible to run 'update.php', but it will not even be possible to clear the cache via the user interface, as the site will be down.

I had this issue when updating 10.2.6 to 10.3.1 and fixed by just cleaning cache. Thanks to @Kasey_MK for the idea.

Same here, drush updb did the trick.

Resolved with DB Clear caches ..
