error listing tags: %v

Error message

error listing tags: %v

What it means

DescribeTags failed while performing the deprecated TagOnSubnet ElasticIP lookup (subnet carrying an AssociatedElasticIp tag); this is a raw AWS EC2 API error, not a lookup miss.

Solutions

1. Check EC2 DescribeTags permissions and network access, then retry
2. Prefer AssociatedNatGatewayRouteTable or an explicit allocationID over the deprecated TagOnSubnet mechanism
