1. Using the current tutorial will return a warning after creating the role "my-role:
```bash
WARNING! The following warnings were returned from Vault:
* Detected use of legacy role or policy parameter. Please upgrade to use the
new parameters.
```
To fix this we need to update the command and the query. Correct entries can be found in documentation for the [AWS Engine](https://www.vaultproject.io/docs/secrets/aws/index.html).
2. `vault revoke` to `vault lease revoke`. The command bellow is updated, but the text above it was not.
Looks like the `500` is now a `405`:
```
$ vault read aws/config/root
Error reading aws/config/root: Error making API request.
URL: GET http://127.0.0.1:8200/v1/aws/config/root
Code: 405. Errors:
* 1 error(s) occurred:
* unsupported operation
```
