GITHUB_ENV missing from @actions/core node process.env object

[nomad-mystic]

I'm running into an issue when I try to use core.exportVariable() on version @actions/core@1.2.6.

Describe the bug
GITHUB_ENV is not part of the process.env object when calling core.exportVariable()

To Reproduce
Actions runner environment: https://github.com/nomad-mystic/test-actions/runs/1434434458?check_suite_focus=true
Git Repo: https://github.com/nomad-mystic/test-actions/

Expected behavior
GITHUB_ENV variable should be part of the node process.env object when using the @actions/core module.

Screenshots

Github actions environment:

• runs-on: ubuntu-latest
• matrix: node_version: [14]
• uses actions/checkout@v2

Additional context
If there is something I'm missing here, pointers would be appreciated.

Thanks

The use of sudo here is resetting your environment variables.

You have a couple ways you can address this:

• Do you need to use sudo or can you remove it? Your workflow should work without sudo
• You can pass the env variable into the sudo script or pass it as an input into the node process
• There may be a way to get sudo to preserve your environment variables when executing

I'm going to close out this issue, but if the above steps don't resolve it, please let me know and we can reopen it!
