Description
Facing the following issue when trying to use "ng deploy":
❌ An error occurred when trying to deploy:
Invalid target string: "github"
Firstly, you can figure out the angular.json from my project: https://github.com/alvachien/knowledgebuilder/blob/master/angular.json
The configuration 'github' already defined, and "ng build -c github" works as expected.
The angular.json also including the options defined "angular-cli-ghpages".
Secondly, no matter run "ng deploy --configuration=github" or "ng deploy --build-target=github" results in same issue.
Could you give me a hint to make it work?
Now I using a workaround by a own NPM script: "deploy-github": "ng build -c github && git push origin :gh-pages && git subtree push --prefix dist origin gh-pages"
