Error in sending reminders to participants of the agreement in Adobe Sign

Hello All,

I am working on a process to send documents for signature using Adobe Sign. Have used Adobe Sign activity package and configured the process of creating Transient document and sending the document for signature.

Wanted to send reminder if the document is not signed with in a specific time, so I have used Invoke Adobe Sign Operation activity and passed Participant ID to send the reminder.

I am facing issue in executing this activity with the required parameters passed. Have attached screenshots of the activates and input parameters used.

Also note the same input parameters when passed in Adobe Sign application swagger, I am able to send the reminder.

Any help would be highly appreciated!

Thank you!
Best regards
