Hello!

I am trying to make a simple workflow with two actions - one to set a value of a column and another to start another workflow. This workflow is for a document library and the column I'm changing the name of is the "Title" which links to the excel that I am generating. I am able to successfully set the name of the Title but the workflow gives me an "unknown error" before it can start the second action. Any help would be appreciated, thank you!

tldr;  Workflow progress page shows that the "Set Field Value" action for a Title field of document library is green and completed (which it is) but will error out before it starts the next action.
