Postgres's deployment to EKS causing error - amazon-web-services

Question

I have been working on a project with Postgres. I want to add this to EKS. my deployment is giving me an error as:
Warning FailedScheduling 29s default-scheduler 0/2 nodes are available: 2 pod has unbound immediate PersistentVolumeClaims. preemption: 0/2 nodes are available: 2 Preemption is not helpful for scheduling.
I have tried changing the storage capacity but nothing worked.
Various components of the YAML file are below:
