Yeah, this is not an issue in core. The issue @andileco linked is the solution to remove the errors. Hopefully gets committed soon. 🤞🏼

I'm having the same message but for a different reason. A module is passing a null library but I can't figure out how to track down which. For now I do this which works but obviously no long term solution.

if($library != null) { $final_libraries[$library] = $library; }

It would be great if we could provide a more helpful error message to help developers fix the error when it somehow happens.

It seems 🐛 Warning: Undefined array key 1 in Drupal\Core\Asset\LibraryDependencyResolver->doGetDependencies() after update to Drupal 10.2.2 and when views ajax is enable. Active and 📌 AttachedAssets should validate libraries internally Active already exist to improve this.
