cnpg-manager is not permitted to modify role bindings on namespace demo

[redy1064]

I have installed the cnpg operator in EKS within the namespace cnpg-system. When trying to create a postgres database in the namespace demo, only services are created. kubectl events show the message: No matching pods found and api server logs have the error: Unauthorized: system:serviceaccount:cnpg-system:cnpg-manager is not permitted to modify role bindings on namespace demo. Code:400.

Are there any permissions to be added to be able to create the pods for postgres in the demo namespace ?
