The solution video to the bravo scenario is outdated and incomplete. Some of the YAML definitions are oddly outdated.
Furthermore: It does not show, what is needed to fullfill the drupal step in the scenario i.e. is the UI configuration step via Drupal Setup UI necessary? If so: This does not work for me - I get the same error that is described in this topic: Game of Pods: Bravo drupal setup issue - #2 by MysterMask
Suggestion: Provide YAML files in addition to solution videos.
