I resolve problem when remove inputs on action.yml

Glad to see you in Github Community Forum! I notice you have successfully published the actions to the marketplace. Thanks for your answer sharing here. You can refer to official doc here for more details of inputs usage in action yaml: https://help.github.com/en/actions/automating-your-workflow-with-github-actions/metadata-syntax-for-github-actions
