Zend Framework 3 Redirect - php

Question

Background: I am using REST methods only.
I've called a create() method, which returns the id of the record I have created, and I want to call a different controller's get() method with that id.
module.config.php :
namespace PrivateStatement;
use Zend\Router\Http\Literal;
use Zend\Router\Http\Method;
return [
'router' => [
'routes' => [
'privateStatement' => [
'type' => Literal::class,
'options' => [
'route' => '/private-statements/private-statements',
'defaults' => [
'controller' => Controller\PrivateStatementController::class,
],
],
'child_routes' => [
'get' => [
'type' => Method::class,
'options' => [
'verb' => 'get',
'defaults' => [
'modules' => [
],
],
],
'may_terminate' => true,
],
'post' => [
'type' => Method::class,
'options' => [
'verb' => 'post',
'defaults' => [
'modules' => [
],
'params' => [
],
'requestVo' => '',
'controller' => Controller\PrivateStatementCreateController::class,
],
],
'may_terminate' => true,
],
],
],
],
],
'view_manager' => [
'strategies' => [
'ViewJsonStrategy',
],
],
];
In the PrivateStatementCreateController, I have the create() function:
public function create($data)
{
$requiredParams = [
PrivateStatementConstants::COLUMN_PROPERTY_ID,
PrivateStatementConstants::COLUMN_STOCK_UNIT_ID,
PrivateStatementConstants::API_FROM,
PrivateStatementConstants::API_TO,
];
$validRequest = ControllerUtil::verifyRequiredParams($requiredParams, $data);
if ($validRequest) {
$personId = $this->authResult->getIdentity();
$id = $this->model->createPrivateStatementService(
$data[PrivateStatementConstants::COLUMN_PROPERTY_ID],
$data[PrivateStatementConstants::COLUMN_STOCK_UNIT_ID],
$data[PrivateStatementConstants::API_FROM],
$data[PrivateStatementConstants::API_TO],
$personId
);
if ($id) {
return $this->redirect()->toRoute('privateStatement', array('action' => 'get', 'params' => array('private_statement_id' => $id)));
} else {
$this->getResponse()->setStatusCode(Response::STATUS_CODE_400);
}
} else {
$this->getResponse()->setStatusCode(Response::STATUS_CODE_400);
}
return new JsonModel([]);
}
The part I'm currently struggling with is return $this->redirect()->toRoute('privateStatement', array('action' => 'get', 'params' => array('private_statement_id' => $id)));
When I call this an exception gets thrown with the message Part route may not terminate - I honestly don't know how to continue from here - I only need to call the get() function in the PrivateStatementController and return the results.
