gitlab-sidekiq-all-in-1 pod stuck in Init: MountVolume.SetUp failed for volume "init-sidekiq-secrets"

Installed the CNC using the instructions here.

Sidekiq pod remains stuck in Init:0/2

kubectl describe outputs:

MountVolume.SetUp failed for volume "init-sidekiq-secrets" : secrets "KULLnHkzg66ipQPydkAK6yKdT" not found

Already tried deleting the deployment (gitlab-sidekiq-all-in-1) and helm upgrade --install again. Same result.

Any clues to why the secrets are not being created?
