Impossible to determine the class name. Either specify it explicitly or give an object

[phtmgt]

The exception is thrown after the file is successfully uploaded and the system tries to redirect the user back to the page where the form is located.

This seems to be related to issue #737 (737 occurs with VichImageType and I temporarily overcome it by using VichFileType, which gets me here), as the stack trace includes this line:

$view->vars['download_uri'] = $this->resolveUriOption($options['download_uri'], $object, $form); in vendor/vich/uploader-bundle/Form/Type/VichFileType.php (line 159)

Please check if latest release (1.6.1) is good for you

[phtmgt]

Nope, it does not solve it. But it solves issue #737.

Please provide some informations to try to reproduce your issue

Action:

The errors occur with all instances of VichImageType and VichFile Type. However, the images and files are successfully uploaded.

[garak]

Can you try to rename your form field consistently with your entity property? So, name it "profilePhotoFile" and avoid to directly call setter.

[phtmgt]

If I don't directly call the setter, how do I go about uploading the image? Thanks.

Update: I tried your suggestion (setting form field consistently and not calling setter) and the same exception occurs.

[garak]

Just call $form->handleRequest($request), supposing that your entity is bound to your form

[phtmgt]

This works. Thank you. Now I will have to figure out how to have extra fields added to the mapped (bound) form.
