SearchFilter on ElaoEnum values broken in 2.5.5

[BeyerJC]

API Platform version(s) affected: 2.5.5

Description
When using a search filter in 2.5.5 on a field that is a enum (elao) an error occurs
"Error : Call to a member function getValue() on string"

The change that is causing this error is #3331.

How to reproduce
Set up a field with an enum type e.g.

 /**
 * @var MediaEnum
 *
 * @ORM\Column(name="MIME_TYPE", type="mediaEnum", length=255)
 */
 private $mimeType;

and try to filter on that field
$this->request('GET', 'attachments?mimeType=image/jpeg')

I have experienced the same issue.

[kacperjurak]

Same for me. Needed revert to 2.5.4.

[guilliamxavier]

Does 2.5.6 fix the issue?

[maciej-laskowski]

@guilliamxavier Yes, upgrading to 2.5.6 fixed the issue. Thanks!
