EKS - Creating nodegroup

[solpunit]

I am creating a managed nodegroup on EKS with eksctl but it is failing, I have created the eks.pem and using the same path.

2022-03-24 17:53:07 [ℹ] using region ap-southeast-2
2022-03-24 17:53:08 [ℹ] will use version 1.21 for new nodegroup(s) based on control plane version
2022-03-24 17:53:13 [ℹ] nodegroup "my-ng" will use "" [AmazonLinux2/1.21]
