Error 400 in create Call

I’m trying to start a call via the Vapi API, and I’m getting this error: "Couldn’t get tool for hook. toolId a4e835ca-b846-4b23-b748-c1c7a1ed4e39 does not exist." However, the assistant I’m trying to call has no tools assigned to it. My orgID: 61d09b13-129f-4353-9eb3-0e7ee89eb6b8 Assistant ID: 378bbdc9-e255-46ca-b6b9-a6ce06c18961

To fix the error, update your assistant's hooks to remove the reference to the missing tool.
Replace the problematic hook with a simple "say" action like this:

{
  "hooks": [{
    "on": "call.ending",
    "do": [{
      "type": "say",
      "exact": "Thank you for calling. Have a great day!"
    }]
  }]
}

{
  "hooks": [{
    "on": "call.ending",
    "do": [{
      "type": "say",
      "exact": "Thank you for calling. Have a great day!"
    }]
  }]
}

Update your assistant using the PATCH API, and the error should be resolved.
