KMSInternalException The request was rejected because an internal exception occurred. The request can be retried.
KMSInvalidStateException The request was rejected because the state of the specified resource is not valid for this request. This exceptions means one of the following: The key state of the KMS key is not compatible with the operation. To find the key state, use the DescribeKey operation. For more information about which key states are compatible with each KMS operation, see Key states of KMS keys in the Key Management Service Developer Guide.

To identify the cause, see the error message that accompanies the exception.

var response = client.GetKeyPolicy(new GetKeyPolicyRequest 
{
    KeyId = "1234abcd-12ab-34cd-56ef-1234567890ab", // The identifier of the KMS key whose key policy you want to retrieve. You can use the key ID or the Amazon Resource Name (ARN) of the KMS key.
