Hello, I am trying to set up a transfer call tool that transfers the call from one assistant to another. I have added the tool to one assistant and each time I am starting the talk with this assistant, I am getting the attached error message. Assistant with the displayed name exists and is published. I have tried changing the assistant name to assistant ID in the tool settings and adding the tool to both assistants, but it did not help in any way. Can you please guide me to resolve this issue? https://cdn.discordapp.com/attachments/1403281317168156784/1403281317680124006/Screenshot_2025-08-07_183054.png?ex=6896fb11&is=6895a991&hm=99bf20c35a8edc6a0c20e06b62ebe85d2132465846ed81a8769e07bd4f320205&

Try this: Double-check that the

assistantName

in your transfer destination matches the published assistant's name exactly (including case and spaces). For example:

json
{
  "type": "assistant",
  "assistantName": "U7receptionWrzeszcz",
  "message": "Transferring you now."
}

If the error persists, ensure the assistant is published and available in your environment. [See more in the Squads documentation.](https://docs.vapi.ai/squads#usage) Source: - [Squads documentation](https://docs.vapi.ai/squads#usage)

I double checked, the match is exact. Both assistants are published. But how to make sure that it is available in my environment? I have them both published in my assistants tab
