Hi! If you look at this file it has an 'x' on top and an error in twister build that says: Error: Value cannot be null. (Parameter 'ContainerId').

Do you know what the issue is?

because the CI run was cancelled (when there is a new commit on the main, any on-going CI runs on the main will be cancelled).
