Hello,
First of all, thank you for building such a great product — I’m really enjoying using it.
I’m hoping someone can help with an issue affecting a production agent , and I’d really like to avoid having to rebuild the entire role prompt.
Issue summary
One of my agents has suddenly stopped working after previously functioning correctly. I now encounter the same error even when duplicating the agent.
Duplicate agent details:
Current problems
The agent no longer runs and throws an error
Duplicating the agent results in the same error
I cannot republish the agent after changing the LLM
I am unable to select a voice for this agent
Additional context
Any guidance or assistance would be greatly appreciated. Thanks in advance!
Hello @stevloc
I’ve reported that, and it will be fixed soon.
It’s fixed now. You can now choose the voice you want.

Hi Omar,
Thanks for helping with ERROR: Resource Not Found - Support Help - Retell AI
I’m having the same issue with this, if you could please update this too, I’d appreciate it:

Thanks

Hello @stevloc , should be solved now
Hello,
I have a similar issue: when I try to select any community Cartesia voice:
Error
Resource Not Found. Please check that it exists and you have permission to access it.
It worked yesterday but I’m stuck now today.
Agent ID : agent_e20bc78738ec9ccf086b92298b
LLM ID : llm_9f9431927d17baa613f0ca551f29
Thanks
Can you check again now? If the issue still persists, please share a screenshot.
Hi,
this is what I can share (apparently I cannot share more than one screenshot):
What I also see when I add the community voice (from the add-community-voice endpoint) is:
{voice_provider: “cartesia”, provider_voice_id: “735287ee-ce91-4b08-8de4-63315c5ba1fb”,…}
provider_voice_id: “735287ee-ce91-4b08-8de4-63315c5ba1fb”
voice_name: “Emmanuelle”
voice_provider: “cartesia”
{“status”:“error”,“message”:"Item org_X7qaImcgZzEFBZzd not found in org "}

@Omar_Ashraf Any idea of what can happen?
This happens because you already have the voice
OK thanks. I had not understood that I had to add the custom voice only once and then I could simply reuse it - I systematically used “add custom voice”. Works now, thanks. Problem solved for me.
