Cannot access AWS Lambda console with the error saying 'You do not have sufficient permission. Access denied.

Bunch of questions about your context:

1. Are you using a root account?
2. Are you a part of an organization on AWS - there might be Service Control Policies applied?
3. Are you using a role to try and access Lambda?
4. Are you trying this in the correct region for your account - you might not be allowed to access services in some regions?

You might need to reach your AWS administrators to request permissions to access the Lambda service.
