Evaluation Error: Expected 2 assistant messages but got 1

Hi team, I'm working on creatign an evaluation suite for our assistants and frequently running into issues with the turn based evals, "Expected 2 assistant messages but got 1" or varying. Question: Considering agents are non-deterministic, how can I implement an eval that doesn't fail if the agent says 1 extra line or call tools at different times?...

Add Voice ID manually for RimeAI it's completely broken.

Not a single one of the specific voices where you would hit the copy button and paste it in works at all.

Stuck in the Riley demo

No matter what I do to the prompt, it will not change the output. I'm stuck with this demo for "Riley" That it defaults to when you first create an account. "Wellness Partners" demo, I just can't get out of it. I'm trying to use Rime Groq Assembly AI combo. Changing those options doesn't seem to change anything either....

Test Suite vs Evals

It’s not clear whether the test suite is still supported or not. It works and is used very differently compared to Evals, and there’s no clear update in the documentation about whether it can still be used. According to this page https://docs.vapi.ai/test/test-suites is still active, and the API endpoints still seem to work, but they’ve been removed from the API documentation, even though the Vapi UI still allows us to use them. Is the test suite still supported? Why was it removed from the API docs? What’s the plan going forward?...

Neha Voice Not Selectable in Assistant Configuration

Despite being visible in the Vapi Voice Library, the voice profile “Neha” (Female, Indian American) does not appear in the search bar when attempting to select it under Assistant → Voice Configuration. When typing “Neha” in the voice selection field, the system returns “No voice found”, even though the voice is clearly listed and available in the main Voice Library panel. This issue prevents the user from assigning the Neha voice to an assistant, causing configuration blockage and inconsistent synchronization between the Voice Library and the Assistant Configuration module....

How do i get an end-of-call report for VAPI chat?

Reading through the documentation, there doesn't seem to be a way to "end" a chat so that an end of call report is generated to get the structured data.

Receptionist in squad w/ recording consent

I need the receptionist to first check with the tool/n8n webhook to make sure the person's phone number is on the list. then i need it to run the compliance script and get confirmation they agree to recording, then make the transfer. the end of call webhook is configured on the assistant the call is being transferred to. Thanks in advance. The json for both workflows is attached if you need to look at it. the latest call log is: 019aec28-2b51-7113-a0ea-039d43205900 squad link: https://dashboard.vapi.ai/squads-v2/bad2ef63-78a0-4d4e-8a4d-31bafcf300cf assistant link: https://vapi.ai?demo=true&shareKey=4fe97633-2e81-4493-9feb-8a34592767cc&assistantId=bc7aa79c-e0af-42e4-b5aa-1e73489be085...

VOICE PROBLEM

I'm having a problem with my agent. It's entirely in Brazilian Portuguese, using a native voice from 11labs. When I call it, the voice is completely buggy, with a strange accent, and unreadable. However, when I use VAPI's "Talk to Assistant," the voice is perfect, with no accent or speech errors. Can anyone help me? Do I need to make any specific settings?
