Redis – Terraform AKS error: services "azure-vote-back" already exists, how to deal with it?

In Terraform I wrote a resource that deploys to AKS. I want to apply the terraform changes multiple times, but don’t want to have the error below. The system automatically needs to detect whether the resource already exists / is identical. Currently it shows me ‘already exists’, but I don’t want it to fail. Any suggestions how I can fix this issue?
