Troubleshooting Amazon Bedrock AgentCore identity and access
Use the following information to help you diagnose and fix common issues that you might encounter when working with AgentCore and IAM.
Topics
I am not authorized to perform an action in AgentCore
If you receive an error that you’re not authorized to perform an action, your policies must be updated to allow you to perform the action.
The following example error occurs when the mateojackson IAM user tries to use the console to view details about a fictional my-example-widget resource but doesn’t have the fictional bedrock-agentcore:GetWidget permissions.
User: arn:aws:iam::123456789012:user/mateojackson is not authorized to perform: bedrock-agentcore:GetWidget on resource: my-example-widget
In this case, the policy for the mateojackson user must be updated to allow access to the my-example-widget resource by using the bedrock-agentcore:GetWidget action.
If you need help, contact your AWS administrator. Your administrator is the person who provided you with your sign-in credentials.
I am not authorized to perform iam:PassRole
If you receive an error that you’re not authorized to perform the iam:PassRole action, your policies must be updated to allow you to pass a role to AgentCore.
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 AgentCore. However, the action requires the service to have permissions that are 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’s policies must be updated to allow her to perform the iam:PassRole action.
If you need help, contact your AWS administrator. Your administrator is the person who provided you with your sign-in credentials.
I am not authorized to perform iam:CreateRole in the console
If you receive an error that you’re not authorized to perform the iam:CreateRole action when creating an AgentCore resource in the AWS Management Console, you need to add additional permissions to your IAM user or role.
The following example error occurs when you create a harness and the console attempts to auto-create the execution role on your behalf:
User: arn:aws:iam::123456789012:assumed-role/MyConsoleRole/user is not authorized to perform: iam:CreateRole on resource: arn:aws:iam::123456789012:role/service-role/AmazonBedrockAgentCoreHarnessDefaultServiceRole-abc12 because no identity-based policy allows the iam:CreateRole action
To resolve this issue, do one of the following:
-
Add an inline policy: Add a policy to your IAM user or role that grants the necessary permissions for the console to create execution roles on your behalf:
{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": "iam:CreateRole", "Resource": "arn:aws:iam::123456789012:role/service-role/AmazonBedrockAgentCore*" }, { "Effect": "Allow", "Action": "iam:CreatePolicy", "Resource": "arn:aws:iam::123456789012:policy/service-role/AmazonBedrockAgentCore*" }, { "Effect": "Allow", "Action": "iam:AttachRolePolicy", "Resource": "arn:aws:iam::123456789012:role/service-role/AmazonBedrockAgentCore*", "Condition": { "ArnLike": { "iam:PolicyARN": "arn:aws:iam::123456789012:policy/service-role/AmazonBedrockAgentCore*" } } } ] } -
Create the execution role manually: Create the role before creating the resource in the console, and then select the existing role instead of allowing the console to auto-create one. For the required trust policy and permissions, see Execution role for running an agent in AgentCore Runtime.
I want to allow people outside of my AWS account to access my AgentCore 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.
