Compilation failed or was cancelled

Help Studio

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:

@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!

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

7

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.

8

I have same error, any news ?

9

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

10
