We are also experiencing this issue on our site which was built on Drupal 8.6 and now upgraded to Drupal 10.0.8. Some of the configs like admin toolbar, advagg, etc.do not have UUIDs, I also doubt it is happening due to those.

Changing to Major as it is a blocker during config export/import.

Webform also triggers this with its default contact form when installing from config.

Don't think a notice qualifies for major. If someone could help me recreate the fatal from the load failures addressed in #4 maybe we can bump it back but I suspect that might be a different maybe related issue. Until then it will also be difficult to create a realistic test for it.

Here's an updated patch for Drupal 10 with just the uuid handling (since I don't know how to recreate and test the load failure) and a test.

This asserts the existing behavior with the undefined property evaluating to null. Is recreating actually correct though? That seems kinda odd.

I don't know if the order matters here. Or if we need to assert it since its probably better tested else where. I would appreciate someone more familiar with the methods chiming in here.

@neclimdul if webform is creating entities without a UUID then that's a bug in webform - no?

this has come back

when developing drupal code to share with others, I would want to remove the uuid
https://drupal.stackexchange.com/questions/295320/best-practice-remove-u...

however, I believe in doing so, it causes the "Undefined index: uuid". This post appears to explain: https://drupal.stackexchange.com/questions/204859/site-uuid-in-source-st...
