# E305

# Missing Parameter

## Example

This error occurs when a required parameter is missing from a function call or operation.

In this example, the `SearchV` function is called without the `k` parameter which is required to limit the number of results.

<CodeGroup>
  ```rust queries.hx theme={null}
  Query searchUsers(vector: [F64]) =>
      users <- SearchV<Document>(vector)
      RETURN users
  ```
</CodeGroup>

## Solution

Provide all required parameters for functions and operations.

<CodeGroup>
  ```rust queries.hx theme={null}
  Query searchUsers(vector: [F64]) =>
      users <- SearchV<Document>(vector, 10)
      RETURN users
  ```
</CodeGroup>
