It seems you didn't added observer name inside <event> tag.

You must have to declare <observer> tag inside <event> tag like below..

<observer name="observer_name" instance="Namespace\Module\Observer\ObserverClass" />

Because it's required, You can check more details in below Schema file..


Hope this will help you!
