Compilation failed or was cancelled

I made a few changes to my automation file and want to publish the library to the Orchestrator. However I continuously get this error popup.

Here is my output:

Thank you
Chris

I have exactly the same issue. :frowning_face:

@Leif

I narrowed the issue down to the automation file (xaml) and had to rebuild it. I hope that information helps you.

I will try doing the same then.Thank you, Chris!
