Laravel 5.5 doing a soap call but getting a Mysqli error?

I am trying to do the following SOAP call:

<soapenv:Envelope xmlns:xsi="http://ift.tt/ra1lAU" xmlns:xsd="http://ift.tt/tphNwY" xmlns:soapenv="http://ift.tt/sVJIaE" xmlns:set="http://ift.tt/2xMFNnV">
   <soapenv:Header/>
   <soapenv:Body>
      <set:SetFile soapenv:encodingStyle="http://ift.tt/wEYywg">
         <Filedata xsi:type="test:Filedata" xmlns:test="XXXXXXXXXXXXX.com">
         </Filedata>
         <Vehicle xsi:type="test:Vehicle" xmlns:test="XXXXXXXXXXXXXXXXXXX.com">
            <Type xsi:type="test:VehicleType">Car</Type>
            <Make xsi:type="test:Make">Tesla</Make>
            <Model xsi:type="test:Model">Model S</Model>
            <!--Optional:-->
            <Licenseplate xsi:type="xsd:normalizedString">1-AAA-111</Licenseplate>
         </Vehicle>
      </set:SetFile>
   </soapenv:Body>
</soapenv:Envelope>

When I do this in SOAPUI everything works great.

So in my Laravel project I am using a SoapWrapper and trying to do this same call from my application.

But I get the following error:

SoapFault

MySqli Error: Column 'type_id' cannot be null

So this is what I do in my SoapController:

public function show()
{
    $this->soapWrapper->add('Name', function ($service) {
        $service
            ->wsdl('XXXXX.php?wsdl')
            ->trace(true)

            ->options([
                'login'     => 'login',
                'password'  => 'passsword'
            ]);
    });

    // Without classmap
    $response = $this->soapWrapper->call('Albatros.SetFile', [
        'Type'          => 'Car',
        'Make'          => 'Teska',
        'Model'         => 'Model S',
        'Licenseplate'  => '1-AAA-111',
    ]);

    var_dump($response);
    exit;
}

In my routes for testing I have

Route::get('testsoapcalls', 'SoapController@show');

So when I surf to /testsoapcalls I get the error, unfortunately
