Use the following information to help you diagnose and fix common issues that you might encounter when working with Resource Explorer and AWS Identity and Access Management (IAM).

If the AWS Management Console tells you that you're not authorized to perform an action, then you must contact your administrator for assistance. Your administrator is the person that provided you with the credentials you used to attempt this operation.

For example, the following error occurs when someone assumes the IAM role `MyExampleRole` tries to use the console to view details about a view but does not have `resource-explorer-2:GetView` permission.

```
User: arn:aws:iam::123456789012:role/MyExampleRole is not authorized to perform: resource-explorer-2:GetView on resource: arn:aws:resource-explorer-2:us-east-1:123456789012:view/EC2-Only-View/1a2b3c4d-5d6e-7f8a-9b0c-abcd11111111
```

In this case, the person using the role must ask the administrator to update the role's permission policies to allow access to the view using the `resource-explorer-2:GetView` action.

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.
