Answer 1

I was getting the same error, after 2 hours I realized I had missed:
enctype="multipart/form-data" in the form

Answer 2

You have to add
enctype="multipart/form-data" - in the form, so you can use function like extension() or validator like
"mimes : png , jpg , jpeg"

Answer 3

Remove this line (it seems you do not use it anyway):
->getClientOriginalExtension();
So this should work:
public function store(AvatarUploadRequest $request, UserService $userService) {
$user = $request->user();
try {
$file = $request->file('avatar');
$file = url("/avatars") . "/" . $user->uuid . ".jpg";
$destinationPath = "avatars";
$user->avatar = $request->file('avatar')->move($destinationPath, $file);
$user->avatar = $file;
$user->save();
$userService->updateAvatar($user, $file);
} catch (\Exception $e) {
return jsonApiResponse([
'avatar' => $e->getMessage(),
], 422);
}
return jsonApiResponseWithData($user, 201);
}
