Working on Symfony form that has a file upload and got the above error when I try to save it.
The form is build from entity which has the following format:

class MemberFile
{
    /**
     * SymfonyComponentHttpFoundationFileUploadedFile object
     */
    protected $file;
    /**
     * @ORMId
     * @ORMColumn(name="file_id", type="integer")
     * @ORMGeneratedValue(strategy="AUTO")
     */
    protected $fileId;
    
    /**
     * @ORMColumn(type="string", length=255)
     */
    protected $path;
   // additional member variables and getters and setters goes here...
   .....
    public function upload()
    {
        if (null === $this->file)
            return;
        $this->getFile()->move(
                $this->getUploadDir(), $this->file->getClientOriginalName()
        );
        $this->setSize($this->file->getSize());
        $this->setFileType($this->file->guessExtension());
        $this->path=$this->file->getClientOriginalName();
        $this->file=null;
    }
}

And the form is constructed inside the controller in such a way

$member_file=new MemberFile();
        $form=$this->createFormBuilder($member_file)
                ->add("file")
                ->add("save", 'submit')
                ->getForm();

Right after the appropriate action is requested, I called $member_file->upload() after validation to get the above error..

How I solved it..
1. I checked if the file has been properly uploaded despite the error
-> yes it was uploaded
2. Checked if the original tmp file is still intact –
-> NO and BINGO!
Since the file has been moved, the subsequent operations on $this->file can not be done appropriately.
Solution
Just move those operations before you call move file..

    public function upload()
    {
        if (null === $this->file)
            return;
        $this->setSize($this->file->getSize());
        $this->setFileType($this->file->guessExtension());
        $this->path=$this->file->getClientOriginalName();
        $this->getFile()->move(
                $this->getUploadDir(), $this->file->getClientOriginalName()
        );
        $this->file=null;
    }
