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:

 {
   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'
          }
        ]
      }
    }
}
