WebAPI Error: Class \"\\Vendor\\Module\\...\\FooBar[]\" does not exist #40018
Description
Summary
I am trying to use the REST Web API to return a collection of a certain interface.
The docs specifically say:
Any parameters or return values of type array can be denoted by following any of the previous types by an empty set of square brackets []
And provide the example:
A return which is an array of objects of type \Magento\Customer\Api\Data\CustomerInterface:
@return \Magento\Customer\Api\Data\CustomerInterface[]
Vendor\Module\Api\FooRepositoryInterface:
namespace Vendor\Module\Api;
interface FooRepositoryInterface
{
/**
* @param string $foo
* @param string $bar
* @return \Vendor\Module\Api\Data\FooInterface[]
* @throws \Magento\Framework\Exception\NoSuchEntityException
*/
public function getStatus($foo, $bar);
}
Vendor\Module\Api\Data\FooInterface:
<?php
namespace Vendor\Module\Api\Data;
use Magento\Framework\Exception\LocalizedException;
interface FooInterface {
/**
* @return ?int
* @throws LocalizedException
*/
public function getId();
//...........
}
Vendor\Module\Model\FooRepository:
<?php
namespace Vendor\Module\Model\Api;
use Vendor\Module\Api\FooRepositoryInterface;
use Magento\Framework\Exception\NoSuchEntityException;
class FooRepository implements FooRepositoryInterface
{
// ..........................
/**
* @inheritdoc
*/
public function getStatus($foo, $bar)
{
return $this->FooCollectionFactory->create()
->addFieldToFilter('foo', ['eq' => $foo])
->addFieldToFilter('bar', ['eq' => $bar]);
}
// ............
}
When calling the API it gives me the error:
"message": "Class \"\\Vendor\\Module\\Api\\Data\\FooInterface[]\" does not exist",
"code": -1,
"trace": "#0 \/var\/www\/html\/vendor\/magento\/framework\/Reflection\/MethodsMap.php(166): ReflectionClass->__construct('\\\Vendor\\\\...')\n#1 \/var\/www\/html\/vendor\/magento\/framework\/Reflection\/MethodsMap.php(115): Magento\\Framework\\Reflection\\MethodsMap->getMethodMapViaReflection('\\\\Vendor\\\\...')\n#2 \/var\/www\/html\/vendor\/magento\/framework\/Reflection\/DataObjectProcessor.php(92): Magento\\Framework\\Reflection\\MethodsMap->getMethodsMap('\\\\Vendor\\\\...')\n#3 \/var\/www\/html\/vendor\/magento\/framework\/Webapi\/ServiceOutputProcessor.php(126): Magento\\Framework\\Reflection\\DataObjectProcessor->buildOutputDataArray(Object(Vendor\\Module\\Model\\ResourceModel\\Foo\\Collection\\Interceptor), '\\\\Vendor\\\\...')
Examples
It seems that when it calls ReflectionClass() it puts the [] brackets in, I think it's supposed to be stripped first.
