Ive inputed all the correct values into the three fields the action has available:
Document Set Name - gave it a name of "Agenda_005" (I tried without the "_" and had same error
Target List - Pointed it to the absolute URL of the library and also tried the name "Shared Documents"
SharePointSite URL - Pointed it to the absolute URL of the site
I've enabled Document Sets on the library and even have one in there saved. The error I get is:
"Expression value is invalid. Specified value has invalid Control characters."
I've closed the ticket on the same issue you opened. The last suggested actions were (it might be helpful for others who encounter the same error):
We cannot find the request in the logs, so I can guess the error can be related to Microsoft Flow.
May I ask you to create another test flow with the only one "Create Document Set" action and try to run it? I wonder will you get any new errors, also I would appreciate if you provide TraceId of the request from outputs section.
Additionally, could you please ensure that you are using the correct API key that was generated Plumsail Account?
