I have the following error: "Argument 1 passed to AppServiceFileUploader::upload() must be an instance of SymfonyComponentHttpFoundationFileUploadedFile, string given"

I applied the solution found in this post but it did not change anything. Quite normal, it's not excactly the same error. Can anyone help me please ?

My goal here is to attach multiple documents to a company from the company screen.

I have been trying to solve the problem since yesterday morning. Now, it's time for me to make a break away from keyboard for 1 or 2 hours ...

Here is the code:

Document entity

namespace AppEntity;



use DoctrineORMMapping as ORM;



/**

 * @ORMEntity(repositoryClass="AppRepositoryDocumentRepository")

 */

class Document

{

    /**

     * @ORMId()

     * @ORMGeneratedValue()

     * @ORMColumn(type="integer")

     */

    private $id;



    /**

     * @ORMColumn(type="string", length=255)

     */

    private $fichier;



    /**

     * @var UploadedFile

     */

    private $file;



    // ...

}

Entreprise entity

namespace AppEntity;



use DoctrineCommonCollectionsArrayCollection;

use DoctrineORMMapping as ORM;



/**

 * @ORMEntity(repositoryClass="AppRepositoryEntrepriseRepository")

 */

class Entreprise

{

    /**

     * @ORMId()

     * @ORMGeneratedValue()

     * @ORMColumn(type="integer")

     */

    private $id;



    /**

     * @ORMOneToMany(targetEntity="AppEntityDocument", mappedBy="entreprise", orphanRemoval=true, cascade={"persist"})

     */

    private $documents;



    // ...



    public function __construct()

    {

        $this->documents = new ArrayCollection();

    }



    // ...



    public function getDocuments()

    {

        return $this->documents;

    }



    public function addDocument(Document $document)

    {

        if (!$this->documents->contains($document)) {

            $this->documents = $document;

            //...

        }



        return $this;

    }



    public function removeDocument(Document $document)

    {

        if ($this->documents->contains($document)) {

            $this->documents->removeElement($document);

        }



        return $this;

    }

}

        ]);

    }

PS : Sorry if my english is not good enough but if you want, you can answer in french.

I had the same issue and solved it by removing the type casting in the getFile() and setFile() in the entity. I suppose this is located in your Document entity.

Look for:

public function getFile(): ?string

{

    return $this->file;

}



public function setFile(string $file): self

{

    $this->file = $file;



    return $this;

}

and replace it with

public function getFile()

{

    return $this->file;

}



public function setFile($file): self

{

    $this->file = $file;



    return $this;

}

This will make sure that the file property will have an Instance of the UploadedFile class instead of invoking the __toString method of the same class (due to casting of type to string).
