MS Flow has a very useful "Configure run after" action that you can configure to run if there is an error in the flow. I can't find anything similar in Nintex Workflow Cloud - how can I get it to alert me if a workflow fails?
Apologies for the late response, hopefully you've found your answer in the mean time!
In case you haven't already, with administrator access:
Head to Settings > Alerts (https://[yourtenant].workflowcloud.com/dashboard/settings/alerts) to set up alerts when workflow instances fail, and the intended audience.
Hope this helps!
So just gonna be honest here. Building a workflow to run after it fails is building a poorly designed workflow.
Of course you can't design for every use case so error handling is good, but in theory you'd want to build the workflow to fail gracefully, or end in completion by doing something other than just failing. Also alerts can be setup such that if a workflow does fail, then you can get notified to look into that.
