Unable to delete resources (ENI issue -- no permission to do so?)

Question

Hi. I've seen a similar question/case regarding this, but I am at a loss of what to do.

I am trying to clean up all my resources, and I am unable to detach/delete my subnets, and ENI (other resources).
 
I cant detach my ENI, it claims I don't have permission even when logged in with the root user. 
I do not have a load balancer, nor do I have any resources that are using the ENI. 
It appears that this is an issue with AWS on the backend; that they have yet to recognize or find a solution. It is very frustrating to spend multiple hours to just try to delete my resources, presenting false claims.

Can someone please advise on what I must do here? I don't see why this hold exists. 
AWS should provide a simple option to delete all resources if desired.

Hi,

This typically mean there is still a service that has a dependency on this ENI. Can you select that ENI in the console and check the Description in the Details to see if its used by a specific service?
If the ENI was created by Lambda, you can try this: https://aws.amazon.com/premiumsupport/knowledge-center/lambda-eni-find-delete/

Also please review this question as well: https://repost.aws/questions/QUMb4SZkicQ8GiA6wED7BdCQ/unable-to-detach-or-delete-network-interfaces

Hi John, Thanks for responding. As you mentioned, I did check the details and discovered it was connected to an ECS cluster. All set. Thanks!
