In 2019.10.x and higher version Studio triggers an error when publishing some workflows: "workflow contains invalid characters" .
In 2019.4 and lower version, some workflows could properly be published to Orchestrator.
After upgrading Studio to 2019.10.x or higher, the same workflows are retrieving an error message when publishing it. The error is: "workflow contains invalid characters".
- This is because the Nuget version is updated in Studio, which enforces some naming convention, then spaces and special characters like "Hyphens" are no longer allowed. This was also officially documented in 2019.10.2 What's New .
