I've started seeing

error: unable to validate AWS credentials

after my ECS task deployments, but they seem to have completed correctly:

awsx:x:ecs:EC2TaskDefinition$aws:ecs/taskDefinition:TaskDefinition (QaWeb)
    error: unable to validate AWS credentials. Make sure you have: 

 	 • Set your AWS region, e.g. `pulumi config set aws:region us-west-2` 
 	 • Configured your AWS credentials as per <https://pulumi.io/install/aws.html> 
 	 You can also set these via cli using `aws configure`.

Did you recently upgrade your aws provider to the new MAJOR release?

Yes, I did

Assuming you're using the aws classic provider, the behavior of the underlying terraform provider has changed.

Yea i have a mix of both classic and native

Among other breaking changes, essentially if you have a profile that's used, but you're trying to use environment variables to override, that won't work any longer.

we're setting env vars for

AWS_ACCESS_KEY_ID

and

AWS_SECRET_ACCESS_KEY

Do you also have

aws:region

in your Stack config?

yes i do, and also

aws-native:region

Try deleting

aws:region

and try using

AWS_PROFILE

as an environment variable and see if that works

Ok will try, thanks for the tip and the info about the tf provider

Thanks again for pointing me in the right direction. I was unable to get this working even after removing the config and trying to use the env vars instead. When I did that, i was able to resolve the initial problem above but that created a new problem that was complaining about not having a region set for

awslogs

on my ECS tasks (even though I was never even customizing the logConfiguration). Simplest solution was to just downgrade to an older version of the aws package for now

Are you using

aws.sdk

at all?
