@ahcorde Thank you for the fix!
Could you please adjust your commit message and add the prefix iox-#2266 (it links to the issue I created for your fix.)

You can do this by

git commit --amend
# add iox-#2266 in front of your commit message
git push -f

The background is that we are a project that also runs on a safety-critical system, and therefore, we need to trace every commit message to a GitHub issue.
