"Error: release-please failed: Error adding to tree" when extra-files contains a Github Action / Workflow .yml file

TL;DR

As part of the release process, I wanted to update a constant defined in a reusable Github workflow. If this file is added to extra-files, it causes an extremely ambiguous exception to be thrown.

For example:

"extra-files" : [
   ".github/workflows/some-workflow.yml"
]

The solution is to not try and update workflow files via release-please directly.

Expected behavior

I expected the file to be updated.

Observed behavior

The action throws an exception.

Action YAML

The release-please workflow can be found here: https://github.com/launchdarkly/lua-server-sdk/blob/main/.github/workflows/release-please.yml

Additional information

Note: in the log output, I had to fork the action and add extra debug logs. This is because the action doesn't log the actual Github error that is returned in the "Error adding to tree: " condition.

See here for (what I believe is) the underlying cause of the error: https://github.com/orgs/community/discussions/35410#discussioncomment-7645702
