is this a bug in the native provider that I should file, and then switch over to classic for this?

in this case it was adding line 33 here:
```16 task_definition = ecs.TaskDefinition(
17     resource_name='winnie-web-task-{}'.format(pulumi.get_stack()),
18     requires_compatibilities=['FARGATE'],
19     cpu='1024',
20     memory='2048',
21     container_definitions=[
22         ecs.TaskDefinitionContainerDefinitionArgs(
23             name='nginx',
24             image='<http://755158074228.dkr.ecr.us-west-2.amazonaws.com/winnie-nginx:1.0.4|755158074228.dkr.ecr.us-west-2.amazonaws.com/winnie-nginx:1.0.4>',
25             essential=True,
26         ),
27     ],
28     network_mode='awsvpc',
29     runtime_platform=ecs.TaskDefinitionRuntimePlatformArgs(
30         operating_system_family='Linux',
31     ),
32     execution_role_arn='arn:aws:iam::755158074228:role/ecsTaskExecutionRole',
33     task_role_arn='arn:aws:iam::755158074228:role/winnie-web',
34 )```
but I've been encountering a number of similar errors the last day, where I add or remove or change a field in something, pulumi attempts to update it, and aws returns an api error

so the question is more to the general rather than this specific circumstance

(I wrote my first pulumi code yesterday, so it's also entirely possible I'm just doing something very wrong here)

That is probably a bug in AWS Native. I'd suggest filing a GH issue. Just make sure you have a minimal but complete example to make it easy for our engineers to repro: <https://github.com/pulumi/pulumi-aws-native/issues>

Thanks, will do.  (Sorry, got deathly sick last week and am just getting back to work again)

No worries! Feel better and we greatly appreciate your feedback!
