Toggling over to the Amazon Lex V1 Console

Unfortunately this did not resolve my issue. I still cannot load the v1 console. I think I have all the permissions I need to access, but the answers above doesn't explicitly state what permissions are required

This appears to be an access or permissions issue with the Amazon Lex V1 console. When you're unable to load the Amazon Lex V1 console properly (seeing only a blank screen with menus), it's likely due to insufficient IAM permissions.

To resolve this issue, you should check the following:

1. Ensure your IAM user or role has the necessary permissions to access Amazon Lex V1 resources. You may need permissions for actions like viewing bots, aliases, and other Lex resources.

2. Check if you have the iam:PassRole permission, which is often required when working with Amazon Lex. This permission allows you to pass a role to the service. Without this permission, you might encounter access issues that prevent the console from loading properly.

3. If you're not the AWS account administrator, contact your administrator to review and update your permissions as needed.

4. Verify that you're accessing the console in a region where Amazon Lex V1 is available.

5. Try clearing your browser cache or using a different browser to rule out any client-side issues.

Remember that Amazon Lex V1 will no longer be supported after September 15, 2025, so you might want to consider migrating to Amazon Lex V2 if possible.
