How to use AWS code artifact using serverless framework

I want to upload my serverless package in AWS Code Artifact using :

    sls package --package target/dev --verbose --stage dev
    aws codeartifact login --tool twine --repository XX --domain XX --domain-owner XX --region XX
    twine upload --repository codeartifact target/dev/*

But I am getting the following error:

    ERROR    InvalidDistribution: Unknown distribution format: 'cloudformation-template-create-stack.json'

Is it possible to upload a serverless package to AWS Code Artifact or Am I missing something?

It should be the same problem using Pypi

Thanks

CodeArtifact aims to create managed artifact repository service:

You can use CodeArtifact with popular build tools and package managers such as the NuGet CLI, Maven, Gradle, npm, yarn, pip, and twine.

With that in mind, sls package doesn't not create a valid package format for any of these build tools and pacakge managers.

The Serverless Framework CLI generates deployment artifacts for AWS. These artifacts are uploaded to an Amazon S3 bucket, and the deployment via AWS CloudFormation will reference these artifacts.

The use case you described is not the "correct" one for CodeArtifact.

If you want, you can make it work. Run sls package and modify the output folder to be a valid twine/pypi package: https://www.geeksforgeeks.org/how-to-publish-python-package-at-pypi-using-twine-module/, but that is not what sls CLI was built for.
