After I install the "WFM Time-off HRIS integration" and configured the HRIS(Workday) credentials, its unable to create a data action "Custom Auth Action" and when I try to open, it throws an error " The specified Action was not found."
Dev looked into the error and what they found was that there was a bad workflow setup that was detected as part of validation.
The exact error is: Error: Required property OutputVariables was not found
Since I remember you tested all the data actions and you were able to successfully authenticate to the HRIS, then there is more than likely something wrong with the workflows.
