commit-pinned-digest fails with fatal: could not read Username for 'https://github.com'

After following the guide for certifying an operator, I've hit this and have been unable to fix it.

[commit-pinned-digest : commit-changes] + '[' false = true ']'
[commit-pinned-digest : commit-changes] + git config --global user.email mturek@redhat.com
[commit-pinned-digest : commit-changes] + git config --global user.name mjturek
[commit-pinned-digest : commit-changes] + DIRTY_FLAG=true
[commit-pinned-digest : commit-changes] + echo true
[commit-pinned-digest : commit-changes] true
[commit-pinned-digest : commit-changes] + '[' true == true ']'
[commit-pinned-digest : commit-changes] Commit changes to temporary branch
[commit-pinned-digest : commit-changes] + echo 'Commit changes to temporary branch'
[commit-pinned-digest : commit-changes] + TEMP_BRANCH=main-pinned
[commit-pinned-digest : commit-changes] + git checkout -b main-pinned
[commit-pinned-digest : commit-changes] Switched to a new branch 'main-pinned'
[commit-pinned-digest : commit-changes] + git add -u
[commit-pinned-digest : commit-changes] + git commit -m 'Pin the operator manifests'
[commit-pinned-digest : commit-changes] [main-pinned 1db741b] Pin the operator manifests
[commit-pinned-digest : commit-changes]  1 file changed, 7 insertions(+), 3 deletions(-)
[commit-pinned-digest : commit-changes] + git push origin main-pinned -f
[commit-pinned-digest : commit-changes] fatal: could not read Username for 'https://github.com': No such device or address

I've added the github-ssh-credentials and github_api_secretsecrets mentioned in the docs to my cluster, but no luck. I've tried setting the git_repo_url to git@github.com:mjturek/certified-operators.git as this task seems to be setting up for SSH authentication but then the clone step fails.
