Hi, I'm trying to query an AWS Athena table to build an asset on Dagster Cloud (Serverless). I'm using the env vars AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY and AWS_DEFAULT_REGION to provide authentication on the workers, but I'm getting authentication errors on Dagster Cloud, indicating that my code tried to access another AWS account (maybe the one dagster is using to run the container?). Anyone else ran into similar issues? PS: my main region is us-east-1 and I saw that the serverless ecs service is running on us-west-2.
