This issue has been resolved and workflow actions are working again without error. A tool within our infrastructure became unresponsive which prevented workflow actions to occur. We've resolved the issue and going forward we're investigating what caused and ways to prevent in the future; including additional alerts. Apologies for the inconvenience.
