Yarn fails to install from CodeArtifact

Question

I am working on a npm module and I setup codeartifact. I logged in using the standard aws cli login command and then published using "yarn publish". So far so good.  
When I use yarn install in my test app I get the following error:  
  
error An unexpected error occurred: "https://artifact-6c-XXXXXXXXXX.d.codeartifact.us-east-1.amazonaws.com/npm/npm-repo/aws-sdk: Unauthenticated: request did not include an Authorization header. Please provide your credentials.".  
  
If I do "npm install" it all works and grabs the module as well as the dependencies. I see the CodeArtifact populated with all the dependencies.  
  
I tried deleting all lock files, node_module, yarn cache etc but npm succeeds and yarn fails. It seems it is not picking up the token.  
npm version 7.15.1  
yarn version 1.22.10  
OS: Ubuntu 20.04.2 LTS  
  
What am I doing wrong? I would prefer to use yarn if possible.

Thanks for posting this answer. We'll get the CodeArtifact User Guide updated with instructions for Yarn 2.

I was able to get Yarn 2 working with AWS CodeArtifact.  
Go here to instructions how to install Yarn 2. https://yarnpkg.com/getting-started/install  
  
First I created a script that exports a variable with the CodeArtifact token.  
export CODEARTIFACT_AUTH_TOKEN=`aws codeartifact get-authorization-token --domain artifact-domain --domain-owner 123456789012 --query authorizationToken --output text`  
  
I created a file in the root of the repo  .yarnrc.yml with the following:  
  
yarnPath: ".yarn/releases/yarn-berry.cjs"  
nodeLinker: "node-modules"  
npmRegistryServer: "https://artifact-domain-123456789012.d.codeartifact.us-east-1.amazonaws.com/npm/npm-repo/"  
npmAlwaysAuth: true  
npmAuthToken: ${CODEARTIFACT_AUTH_TOKEN}  
  
So now when I do _**yarn install**_ it authenticates correctly against CodeArtifact.
