User arn:aws:iam::886264053901:user/kk_labs_user_303094 is not authorized to perform: iam:CreatePolicyVersion on resource: policy arn:aws:iam::886264053901:policy/iampolicy_mariyam because no identity-based policy allows the iam:CreatePolicyVersion action
Unfortunately the “engineer.kodekloud.com” type URLs don’t identify the KKE labs very well. Could you please give us the full name of the lab – this will help us look this up and figure out what’s going on here.
Not sure why you had to delete the policy (guessing you needed to change something), but I used the following guide to doing this task, and it worked flawlessly – the policy was created, and grader passed it. It may be that we don’t permit deletion of IAM policies, and that was the error you got as a result.
Please try the lab again; I would guess it will work.
