I'm trying to use the AWS Native module to make an ECS Task Definition and service.

I gave up on the service because I kept getting.

error: unrecognized resource type (Check): aws-native:ecs:Service

and now I'm getting

    error: unrecognized resource type (Check): aws-native:ecs:TaskDefinition

for one of my task definitions, but not the other, both of which use similar code.

Can anyone help me understand what this error means?

hmmm I think this might be a provider issue. I think I've got it wrong and I'm trying to use a aws (Classic) provider to launch aws-native resources, which will clearly not work.

I shall try making an aws-native provider and report back if it works

Yes, that was my error.
It seems to work much better with the correct provider.
