Howdy Philip, I hope you're doing well, been a while. I hit this issue and there's a few things about it which might be interesting.
1. The workflow works in some cases
2. In certain cases (still working on identifying them), I get the error being discussed
3. SLG1 shows an auth failure on GRAC_ACTN, which I'm not buying because that auth is only for the HOLD button in the other actions drop down
The task in the workflow config has been set to a General task.
Any updates on this?
Thanks,
Santosh
