SerializationException with ECS Fargate Tasks

Bug

What did you do?

Attempted to run traefik using the ecs backend. We are currently utilizing a mix of Fargate and EC2 tasks. Verified that traefik starts up normally when only EC2 tasks are present, but fails when any Fargate tasks exist within the cluster.

What did you expect to see?

Traefik starting normally.

What did you see instead?

Hi @gsoyka,

Thanks for your interest in Træfik.

I think your issue is fixed by #3379.

The fargate support has been added in Traefik v1.7. It is not available in v1.6.

Could you please test with Traefik v1.7
