@Joris.Jan.de.Koning In your project folder take a backup of project.json file and delete project.json file and run

Tried it, but unfortunately still results in the same error.
Is there maybe a way to restore this workflow through the version I’ve published to the Orchestrator previously?

I’ve solved it by contacting our ITD department and let them perform a file restore with backups that had been made on the server. Luckily it works again! :slight_smile:

Indra thanks for your help!
