It is marked as urgent in our internal ticket system (tracked as ADO-404) so it should be fixed fairly soon. You can still use the node if you copy / paste it from another workflow. While not ideal you can copy the node below and paste it into your workflow if needed as well.
Error: The workflow has issues and can for that reason not be executed. Please fix them first.
