Hi, I am trying to create a Code Tool and my code under the code snippet is correct and I can successfully test it, but when I added the parameters a warning sign appears and doesn’t go away although everything looks correct and I cannot save my changes. Does anybody know what that is about and can help? I think it is a general bug. Thank you in advance! https://cdn.discordapp.com/attachments/1447982948547690658/1447982949055205511/IMG_8267.jpg?ex=6940daf5&is=693f8975&hm=dd51dc32b7e38436cb20d3d202fb2e4eb1f04b53dbac3760d5b11d10d7e7d69b& https://cdn.discordapp.com/attachments/1447982948547690658/1447982949533225282/IMG_8266.jpg?ex=6940daf5&is=693f8975&hm=8bd48710d64ffa62f32d82cb66fc89f2805273495dd82494ab08dec3be473af1&

It looks like the error is due to the parameter schema needing to be an object with the correct structure. Try using this format for your parameters:

json
{
  "type": "object",
  "properties": {
    "specialty_id": { "type": "number", "description": "Specialty ID" },
    "insurer_id": { "type": "number" },
    "payment_method_id": { "type": "number" },
    "name": { "type": "string" },
    "works_with_adults": { "type": "boolean" },
    "works_with_children": { "type": "boolean" }
  },
  "required": ["specialty_id"]
}

Make sure your schema matches this structure—this should resolve the "expected 'object'" validation error.

I am doing this via the dashboard, not programatically, so I do not have control over the schema, I tried adding an object as a parameter under section Parameters but it led to the same error, is this a bug since it doesn’t happen if I am building a function tool and adding the parameters the same way? @User

Same problem for me https://cdn.discordapp.com/attachments/1447982948547690658/1448180791296262204/image.png?ex=6942e4b6&is=69419336&hm=1ada53caef36ac0ce42069db4e46f4dc658cf7a63d6e32985903073b2d0f7cad&

Try this: In the dashboard, ensure each parameter is added individually (not as a nested object), and double-check that all parameter types match the expected JSON schema (e.g.,

"type": "string"

,

"type": "number"

). If the error persists, it may be a dashboard bug—report it via [Vapi Support](https://docs.vapi.ai/support) or join the [Vapi Discord](https://discord.com/invite/pUFNcf2WmH) for real-time help. Example parameter entry: - Name:

phone_number

- Type:

string

- Required: checked If you still see the error, please share your exact parameter setup with support for further troubleshooting. Sources: - [Custom tools troubleshooting](https://docs.vapi.ai/tools/custom-tools-troubleshooting) - [Vapi Support](https://docs.vapi.ai/support)

is there only a bot replying any real human here?

Hi eliterzieva, It seems you're encountering a validation issue with your Code Tool's parameter setup. To resolve the "expected 'object'" error, make sure your parameter schema is correctly formatted as an object. Here's a sample JSON structure you can follow:

json
{
  "type": "object",
  "properties": {
    "specialty_id": { "type": "number", "description": "Specialty ID" },
    "insurer_id": { "type": "number" },
    "payment_method_id": { "type": "number" },
    "name": { "type": "string" },
    "works_with_adults": { "type": "boolean" },
    "works_with_children": { "type": "boolean" }
  },
  "required": ["specialty_id"]
}

Make sure to double-check that each parameter is added individually with the correct type, and the overall schema format matches the above structure. If you continue to experience issues, it may be related to a dashboard bug. You can report such bugs via [Vapi Support](https://docs.vapi.ai/support) or join the [Vapi Discord](https://discord.com/invite/pUFNcf2WmH) for additional assistance.

Again, I am doing this via the dashboard and I have ZERO control over the schema. Can you please test this in the dashboard and see what is happening or present a viable solution?

I thought I am going crazy, I am experiencing the same error. Form has validation errors: Invalid literal value, expected "object" Click the warning icon to run full validation

No body helps though

their dashboard is broken, only way to build a code tool currently is via API

We are looking into it. Will provide an update soon

any news?
