Hi All,
Please your help. In a Power Automate Flow, I have the action: "Create an Invite."
I need the field: "Survey" be auto-populated, not manually selected in the flow.
I have tried the following syntax,
- msfp_survey,Guid of the Survey
- /msfp_surveies (Guid of the Survey)
- /msfp_surveys (Guid of the Survey)

But I only get error: "BadRequest."
Error: {"ErrorMessage":"System.Exception: CreateInviteRequestHandler::RetrieveAndUpdateFormDetails:: expection while fetching form and cds url ---> Microsoft.FormsPro.Shared.Common.InvalidFormIdException: The input is not a valid Base-64 string as it contains a non-base 64 character, more than two padding characters, or an illegal character among the padding characters. ---> System.FormatException: The input is not a valid Base-64 string as it contains a non-base 64 character, more than two padding characters, or an illegal character among the padding characters. \r\n
Thanks and best regards.
