Github Enterprise Cloud - New node_id format results in "error running command: illegal base64 data at input byte 2" during release creation

[MiliDurasovic]

Describe the bug

We have recently migrated from Github Enterprise to Github Enterprise Cloud and afterwards one of our pipelines, which uses github-release-resource fails during release creation with the following error:

error running command: illegal base64 data at input byte 2

After confirming that all the new URL´s are correct, I dug deeper and noticed that the node_id seems to be now URL-Safe with no = padding and always starts with RE_.
Example: "node_id": "RE_xyzXYZxyzXYZxyzX"

And this seems to be the cause of this error.
Since there was no fallback to DatabaseId for Enterprise, I have tried fixing it locally myself by adding the following fix:

Created a local image and the tests were passing.
Afterwards the release creation was working fine again. But this solution kind of feel like a bandaid on a broken leg, since the underlying issue with the new node_id format is still there.

You guys probably have a better idea on how to handle this without breaking downward compatibility.

Strangely I see no mention of such a change in the release notes and the official API docs still show the old node_id format:
https://docs.github.com/en/enterprise-cloud@latest/rest/releases/releases?apiVersion=2026-03-10#create-a-release
