Describe issue

When running act, my workflows fail if they try to write to GITHUB_STEP_SUMMARY.

I found as a workaround that I can make my workflows work by providing a value through the --env flag:

I searched the code and the only mention of this ENV variable is this line:

act/.github/actions/run-tests/action.yml

Lines 65 to 68 in 932863b

	if(process.env.GITHUB_STEP_SUMMARY) {
	core.summary.addCodeBlock(myOutput);
	await core.summary.write();
	}

Since it's wrapped around an if statement, I'm assuming that it cannot fail.

Not familiar with the code and not a Go developer, but I'm assuming it should be defined there?

act/pkg/runner/step.go

Lines 108 to 111 in 21ea3d0

	(*step.getEnv())["GITHUB_OUTPUT"] = path.Join(actPath, outputFileCommand)
	(*step.getEnv())["GITHUB_STATE"] = path.Join(actPath, stateFileCommand)
	(*step.getEnv())["GITHUB_PATH"] = path.Join(actPath, pathFileCommand)
	(*step.getEnv())["GITHUB_ENV"] = path.Join(actPath, envFileCommand)

Thanks
