longhorn_volume_size error

[clickersmudge]

Hi,
Could you please help me?
Setting "longhorn_volume_size = 20" causes an error.

The given value is not suitable for module.kube-hetzner.var.agent_nodepools declared at
│ .terraform/modules/kube-hetzner/variables.tf:71,1-27: all list elements must have the same type.
