Pipelines: git push gives warning: Your account does not have an email address associated with it Edited

[ob]

We use Bitbucket Pipelines.

We have some release process defined in Pipelines. In this step we create a new git tag and do finally a "git push origin <my-tag-name>".

It works so far, but in the Pipelines console log I see the following Warning message:

remote: Your account does not have an email address associated with it
remote: Please set one by visiting ....

 How can I get rid of this message? Or what's the issue producing this warning?

Thanks for help!
