@Eddie
Thank you for providing the voice ID "sarah." To troubleshoot the issue, I'll need a bit more information:
1. Are you using the correct voice ID in your API request?
2. Could you share the exact error message you're receiving, if any?
3. Have you checked if there are any restrictions or additional configurations required for using "sarah" in your API calls?
Once I have this information, I'll be able to assist you more effectively. If everything seems correct on your end, it might be a good idea to check the API documentation once more to ensure that the voice ID is being used in the proper format and context. If the problem persists, please let me know so we can explore further solutions.
