Neuphonic Voices doesn´t work

Each time I try to use Neuphonic Voices, I get this message.

Remove languageCode from your assistant voice setting.
Neuphonic does not require languageCode

Remove "languageCode" from the "voice" config, Vapi only accepts "provider" and "voiceId" for Neuphonic voices…

When I try updating it through API, it says: "Couldn't Find Neuphonic Voice. If you're using your credentials, check the voice exists in your Neuphonic account. If not, check the voice exists in the provided list"

But I am adding the voiceId as it should be:

{
"voice": {
"provider": "neuphonic",
"model": "neu_fast",
"voiceId": "ea66187e-eef6-4c83-a777-52d15cfdc8e2",
"language": "es"
}
}

Hey! There are two things:

If you are using a VAPI API key, and the voice doesn't exist in our account, you couldn't use it.
In case you are using your own voice (a custom voice), you have to add your API key first and then import the voice by adding it to your organization inside VAPI. This way you will be able to use your voice.

Let me know how it goes for you.

Hello??

I am using the vapi integration, but each time I try to use a spanish voice, it throws this error. There is no problem with english voices. Could uou take a look?
