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!

Hello,

recreate the XAML? does anyone have another solution?

Kind regards

Hi,
I found that deleting the DLL and recompiling works as well.

I had this same issue and it was because I had just deleted a workflow that was being called by another workflow in the library.

I have same error, any news ?

wich .dll did you delete, did you solve it, doing that ?

I have same issue and studio version is 23.4.1, Is anyone solved the problem? or any news?
