Checklist

• The PR's target branch is 'hybridgroup:dev'
• I have added tests that prove my fix is effective or that my feature works
• New and existing unit tests pass locally with my changes (e.g. by run make test_race)
• No linter errors exist locally (e.g. by run make fmt_check)
• I have performed a self-review of my own code

If this is a new driver or adaptor:

• I have added the name to the corresponding README.md
• I have added an example to see how to setup and use it
• I have checked or build at least my new example (e.g. by run make examples_check)

If this is a PR for release:

• The PR's target branch is 'hybridgroup:release'
• I have adjusted the CHANGELOG.md (or already prepared and will be merged as soon as possible)

@gen2thomas saw that.. luckily I happen to be on semi-vacation so will check the errors out tomorrow morning :D

@szampardi no worry - after some month of nearly do nothing for gobot I determine also problems with CircleCI, at least on the UI. Hopefully I can solve this or it does not happen on server.

Hi @szampardi , please rebase to dev branch - the CI checks are working.

Thanks Thomas

please rebase to dev branch

well that didn't go as expected :D

[gen2thomas]

From the commit history I think it was a merge not a rebase. After an rebase your commit should be the last (newest) in the history.
