it appears error describing missing variable

errorexception undefined variable: categories.

this means blade template can't see $categories variable using in loop.

check web.php or app/http/controller/file.php blade template being called , sure passing variable along view function.

example

return view('greeting', ['name' => 'james']); // <= passing variable $name string 'james'
