I took over as admin of my department's SharePoint 2016 site at the beginning of the year. I edited a site workflow to add a few more individuals to the notification email that goes out. Up until that point, the workflow ran as scheduled. Ever since I made that edit, the workflow cancels and errors out. I get two notification emails. One states that the workflow was canceled by System Account and a 2nd email states that the workflow errored, "Failed to start". To test this, I built a workflow that just sends a notification email to me. There are no other parameters in the workflow. If I run it manually, the notification goes out. But if I schedule it, I get the two emails I specified above. I had one of my peers do the same thing and get the exact same results.
Is it possible there are permissions somewhere specifically affecting the ability to have scheduled workflows run? I've googled this and find a few results but they all link to a "fix" articel from a few years ago with instructions on clearing the designer cache on SP2010/2013 but nothing on 2016 and I can't find a way to do that based on the instructions provided. Any help is appreciated.
@irish_nate welcome aboard and happy new year. Sorry you're experiencing some difficulties.
You could attempt to restore the workflow to a previous version to see if something weird happened. Out side of that and I hate tossing people over to support and not helping them here, but head over to customer.nintex.com and submit a case there.
@eharris04 Thanks for the reply! I haven't restored previous versions since I overwrote them with the updated workflow. But I created new workflows and had two peers (including the old admin/site creator who had scheduled workflows working fine until 1/1/20) do the same and all three of us have started them manually and they run as expected. But when scheduling them, we all get the same errors. It's a super fun problem so far! Love being pioneers! lol
Something odd.... yea head to customer.nintex.com and submit a ticket. I'll ping a few folks as well and see who gets your a response the quickest.
