Troubleshooting Amazon Lex Identity and Access
Use the following information to diagnose and fix common issues that you might encounter when working with Amazon Lex and AWS Identity and Access Management (IAM.)
Topics
I Am Not Authorized to Perform an Action in Amazon Lex
If the AWS Management Console tells you that you're not authorized to perform an action, contact your administrator for assistance. Your administrator is the person that provided you with your user name and password.
For example, the following error occurs when the
mateojackson
IAM user tries to use the console to
view details about a bot but doesn't have
lex:GetBot
permissions.
User: arn:aws:iam::123456789012:user/mateojackson is not authorized to perform: lex:GetBot on resource: OrderPizza
In this case, Mateo must ask his administrator to update his
policies to allow him to access the OrderPizza
bot
using the lex:GetBot
action.
I Am Not Authorized to Perform iam:PassRole
If you receive an error that you're not authorized to perform the
iam:PassRole
action, then you must contact your
administrator for assistance. Your administrator is the person that
provided you with your user name and password. Ask that person to
update your policies to allow you to pass a role to
Amazon Lex.
Some AWS services allow you to pass an existing role to that service, instead of creating a new service role or service-linked role. To do this, you must have permissions to pass the role to the service.
The following example error occurs when an IAM user named
marymajor
tries to use the console to perform an
action in Amazon Lex. However, the action requires the service
to have permissions granted by a service role. Mary does not have
permissions to pass the role to the service.
User: arn:aws:iam::123456789012:user/
marymajor
is not authorized to perform: iam:PassRole
In this case, Mary asks her administrator to update her policies
to allow her to perform the iam:PassRole
action.
I Want to View My Access Keys
After you create your IAM user access keys, you can view your access key ID at any time. However, you can't view your secret access key again. If you lose your secret key, you must create a new access key pair.
Access keys consist of two parts: an access key ID (for example,
AKIAIOSFODNN7EXAMPLE
) and a secret access key (for
example, wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
).
Like a user name and password, you must use both the access key ID
and secret access key together to authenticate your requests. Manage
your access keys as securely as you do your user name and
password.
Do not provide your access keys to a third party, even to help find your canonical user ID. By doing this, you might give someone permanent access to your account.
When you create an access key pair, you are prompted to save the access key ID and secret access key in a secure location. The secret access key is available only at the time you create it. If you lose your secret access key, you must add new access keys to your IAM user. You can have a maximum of two access keys. If you already have two, you must delete one key pair before creating a new one. To view instructions, see Managing Access Keys in the IAM User Guide.
I'm an Administrator and Want to Allow Others to Access Amazon Lex
To allow others to access Amazon Lex, you must create an IAM entity (user or role) for the person or application that needs access. They will use the credentials for that entity to access AWS. You must then attach a policy to the entity that grants them the correct permissions in Amazon Lex.
To get started right away, see Creating Your First IAM Delegated User and Group in the IAM User Guide.
I Want to Allow People Outside of My AWS Account to Access My Amazon Lex Resources
You can create a role that users in other accounts or people outside of your organization can use to access your resources. You can specify who is trusted to assume the role. For services that support resource-based policies or access control lists (ACLs), you can use those policies to grant people access to your resources.
