Using /auth/aws/identity-accesslist/:instanceID always meet unsupported path error

I logged into Vault through AWS EC2 successfully. Then I try to use the /auth/aws/identity-accesslist/:instanceID endpoint to remove the entry in the accesslist after I restart server so that I could login to vault with EC2 without provide nonce again, however, I always run into unSupported path issue:
curl --header “X-Vault-Token: $TOKEN”

{“errors”:[“1 error occurred:\n\t* unsupported path\n\n”]}

Anyone has any suggestions? I’m using Vault 1.6.0 Thanks.

@acme2016 if you’re using Vault 1.6, use identity-whitelist instead of identity-accesslist
