# Common Errors

This section describes the common errors(assertions) on placing/submitting new orders and cancelling exiting orders.

**Place Order Errors**: Below are the common errors occurs during the verification of order submission.

Example of error thrown from `transact`: 

```javascript
 {
   json: {
      code: 500,
      message: 'Internal Service Error',
      error: {
        code: 3050003,
        name: 'eosio_assert_message_exception',
        what: 'eosio_assert_message assertion failure',
        details: [
          {
            message: 'assertion failure with message: Invalid order type',
            file: 'wasm_interface.cpp',
            line_number: 1075,
            method: 'eosio_assert'
          },
          {
            message: 'pending console output: ',
            file: 'apply_context.cpp',
            line_number: 113,
            method: 'exec_one'
          }
        ]
      }
    }
}
```

The above errors asserts whether the order type in place order is valid or not. Since order type is not valid, it will throw an error "Invalid order type"

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.metalx.com/developers-dex/contract-mappings/common-errors.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
