Problem

You are setting the Model image property to an object of type \\Psr\\Http\\Message\\UploadedFileInterface instead of a string . The Model does not know how to handle the object.

The Slim $request->getUploadedFiles() returns an object of type \\Psr\\Http\\Message\\UploadedFileInterface and not a string .

Solution

To access the image data, first we need to get the stream :

$data = $request->getUploadedFiles();
$uploadedImage = $data['image'];
$uploadedImageStream = $uploadedImage->getStream();

Now that we have the stream , we can read from it chunks just like we would from a file. However, we are just going to fetch all the data at once and set it to the Model property:

$image->image = $uploadedImageStream->getContents();
