Hi, I would like to deploy a SAM application to localstack. I have essentially 3 commands to run a sam build followed by a sam package and sam deploy. The second command upload artifacts to S3 and I would like to have this bucket simulated locally.

So I created it aws s3api create-bucket --bucket my-bucket --endpoint-url http://localhost:4572 and then I executed the sam build command. It worked. Now I have to run sam package that is essentually an alias for aws cloudformation package so I execute.

aws cloudformation package \
    --output-template-file packaged.yml \
    --endpoint-url http://localhost:4581 \ 
    --profile localstack \
    --s3-bucket my-bucket \
    --template-file template.yaml

but I get:

Unable to upload artifact XXX referenced by CodeUri parameter of XXX resource.
An error occurred (InvalidAccessKeyId) when calling the PutObject operation: The AWS Access Key Id you provided does not exist in our records.

before to execute this command I executed aws configure --profile localstack and configured access and secret as dummy and us-est-1as defult region.

Can I use local s3 for this or do I need a real S3 bucket?
