Hello @Sandeep Pradeep , Thanks for using Microsoft Q&A Platform.
The error message indicates that the role for the conversation item is invalid, and that the supported roles are Customer
and Agent
for issue resolution summarization. As per the documentation and the error looks like the supported roles are these so, please add these and try.
So please ensure that the conversation items are assigned with these correct roles: https://learn.microsoft.com/en-us/azure/ai-services/language-service/summarization/how-to/conversation-summarization#get-recap-and-follow-up-task-summarization
I hope this helps.
Regards,
