Description

If REST method typeOut defined then /api-doc throws exception.

How to reproduce:
1. rest.camel.yaml

- restConfiguration:
    component: platform-http
    apiContextPath: /api-doc
    bindingMode: json
- rest:
    id: rest-b339
    get:
      - id: get-c5d3
        path: /account
        to: direct:get-account
        outType: karavan.simple.Account
        bindingMode: json
- route:
    id: route-4956
    nodePrefixId: route-7d3
    from:
      id: from-cad7
      uri: direct
      parameters:
        name: get-account
      steps:
        - setBody:
            id: setBody-0623
            expression:
              groovy:
                id: groovy-782e
                expression: |-
                  def acc = new karavan.simple.Account()
                  acc.setAccountNumber('12345')
                  acc.setAccountName('test')
                  return acc
        - log:
            id: log-bd34
            message: ${body}

2. Java Class

public class Account {

  // Private fields for encapsulation
  private String accountNumber;
  private String accountName;
  private double balance;

  public Account() {
  }

  public String getAccountNumber() {
    return accountNumber;
  }

  public void setAccountNumber(String accountNumber) {
    this.accountNumber = accountNumber;
  }

  public String getAccountName() {
    return accountName;
  }

  public void setAccountName(String accountName) {
    this.accountName = accountName;
  }

  public double getBalance() {
    return balance;
  }

  public void setBalance(double balance) {
    this.balance = balance;
  }
}

3. Run
