Creation of service was not idempotent

I’m running install once

waypoint install -accept-tos -platform=ecs -ecs-region=us-east-1

Then running it for the second time, getting:

❯ waypoint install -accept-tos -platform=ecs -ecs-region=us-east-1
✓ Networking setup
✓ Found existing ECS cluster: waypoint-server
✓ EFS ready
✓ Found existing IAM role to use: waypoint-server-execution-role
✓ Using existing log group
✓ Network load balancer created
❌ Creating server Service...
! Error installing server into ecs: InvalidParameterException: Creation of service was not idempotent.

Is this currently the expected behavior?

Thanks!
