Hm.... $request->image is just a string containing the filename... But how can I achieve this to actually be the file uploaded? On the website I have:
<input type="file" class="form-control" accept=".png" name="image" id="image">

Laravel Validation "image" returns error that uploaded file is not an image.
Hello there! I am currently trying to make a form that lets users create posts and optionally also add images to them. For Validation, I did the following:
$request->validate([
'content' => 'required|max:3000',
'image' => 'nullable|image|mimes:png|max:2048',
'title' => 'required|max:500',
'topic' => [
'required',
Rule::in(["topic1", "topic2",])
]
]);
When I try to submit the form (which does a POST to the Endpoint where the Validation is) it works as long as I don't put an image. But if I put an image, I get an error saying "The image must be an image." Does anyone know what causes this and how I could fix this? I already tried searching for people having similar problems on the Internet but wasn't able to find anything.

The file under validation must be an image (jpg, jpeg, png, bmp, gif, svg, or webp).
Probably mimes is enough if you need only .png files
'image' => 'nullable|mimes:png|max:2048'

I already tried that but the only thing it does is tell me that it has to be a file of type PNG. After some further debugging I noticed that even when removing the Validation, it fails. $request->file('image') is apparently null. After looking at the POST Request sent via DevTools, I cannot find any file or anything. The image value that's sent is again, just a string containing the file name

does your form include enctype="multipart/form-data"?
<form method="POST" enctype="multipart/form-data">

It didn't. And that fixed and made it pass validation. I looked at lots of Articles on File Uploads, and none of them had this in their Examples, which is quite weird. But thank you a lot. I still have some trouble with saving the file, but I will look into this. But at least if finally passes Validation. Thank you a lot!

@Amanar-Marouane remove all the validation for the image, then check what you get in your request
$request->validate([
'image' => 'nullable'
]);
dd($request->all());
