[Solved] KMSKeyNotAccessibleFault: The specified KMS key does not exist, is not enabled or you do not have permissions to access it.

 Error:-

While running the terraform i came across the IAM permission issue which prevented access to the kms key

KMSKeyNotAccessibleFault: The specified KMS key does not exist, is not enabled or you do not have permissions to access it.

Cause:-

The issue is caused because the IAM role being used by terraform is missing the permission of "kms:CreateGrant"

Solution :-

To resolve the issue in the IAM policy please grant the following permission "kms:CreateGrant" to the relevant kms key. that should solve the issue

{  
   "Action": [  
     "kms:Sign",  
     "kms:ReEncrypt*",  
     "kms:GetPublicKey",  
     "kms:GenerateDataKey*",  
     "kms:Encrypt",  
     "kms:DescribeKey",  
     "kms:Decrypt",  
     "kms:CreateGrant"  
   ],
