Hi @KouWakai
unfortunately, there is no that variable.
You can check what are in place Environment variables - GitHub Docs.
Also you can try to check GH marketplace GitHub Marketplace · Actions to improve your workflow · GitHub maybe some actions can help you to achieve your goals.

Depending on the event, it’s possible that what you want is available in the event objects which can be mapped to environment variables using ${{...}} magic.

You could try using toJSON(...) on each of the contexts in a step to see what’s available.

Contexts - GitHub Docs

You can access context information in workflows and actions.

This one is self resolved.

There is no way to get issue title like I asked.

We could get title from payload which comes from @actions/github

like this:

const github = require(’@actions/github’);

    // Get context and payload
    const context = github.context;
    const payload = context.payload;
if (payload.issue && payload.issue.title) {
  return payload.issue.title;
}</code></pre>

Thank you for helping me out:pray:

I couldn’t see reply yesterday for some reason(maybe the replies are meant to be awaiting for approval?)

I’ll check toJSON(...) out.
