jf yarn install - [🚨Error] invalid character 'u' looking for beginning of value

[chkp-roniz]

I am not using scopes in my yarn project (just npmRegistryServer); hence, this line fails since yarn config get npmScopes is
undefined

jfrog-cli-core/artifactory/commands/yarn/yarn.go

Line 323 in a063de8

err = json.Unmarshal([]byte(npmScopesStr), &npmScopesMap)

Please skip if undefined and don't try to unmarshal it to JSON

Also, after setting an internal scope in npmScopes, jf yarn install freezes for a long time

# yarn config get npmScopes
{
  internal: {
    npmAlwaysAuth: false,
    npmAuthIdent: null,
    npmAuthToken: null,
    npmAuditRegistry: null,
    npmPublishRegistry: null,
    npmRegistryServer: 'https://artifactory.company.com/artifactory/api/npm/npm/'
  }
}

Hey @chkp-roniz,

I noticed that you're currently using yarn v4.1.1, but it seems that the JFrog CLI doesn't support yarn version 4.x yet. While changing the specific line you mentioned might prevent the CLI from crashing, it's just one of many changes from the previous versions to v4 that needs to be done.

My suggestion would be to downgrade yarn to v3.8.1 if possible. I've tested it with this version of yarn, and it works well. Additionally, you could open a feature request for yarn v4 support, and we'll consider incorporating it into our roadmap.

Let me know if you have any more questions!
