Hi @vtoxi
A problem was found with your pull request:

❌ ERROR: Pull request removes newline from the end of a file.
Please add a blank line to the end of the file.

Please resolve this error. The checks will automatically run again once that is done.

Closing as duplicate of #7196.

@vtoxi in the future please only create one pull request for each submission.

As was already clearly explained in the comments from the bot, there is no need or point in submitting a new pull request after a problem is detected with your existing PR.

What you must do instead is CAREFULLY read the information provided by the bot and then fix the problem. Once you do that, another round of automated checks will be triggered. You can repeat that process in a single pull request as many times as is needed to get it to a fully compliant state. Once your submission passes all the checks it will automatically be accepted by the bot.

You will never fix the problem by submitting the same non-compliant pull request multiple times. That will only waste your time and the time of the humans who maintain this free open source project.

⚠ Repeated irresponsible behavior may result in the revocation of your Library Manager Registry privileges.

Thanks in advance for your cooperation.
