title: Magento 2: Custom Category Attribute - Image Upload Ajax 404
body: <p>I've downloaded the following module (just to save time: <a href="https://github.com/studioraz/magento2-category-image" rel="nofollow noreferrer">https://github.com/studioraz/magento2-category-image</a>) which should add an image attribute to the category page in the admin panel which it does; however, I keep getting the following error when I try to upload an image:</p>
  
  <pre><code>POST https://www.example.com/admin/categoryimage/category_mobile/upload/key/b1da8d66c447c86971b2a9f0f8092b245cb3d4e947cc1f5ba03fc2d79574138f/?isAjax=true 404
  </code></pre>
  
  <p>I've double-checked the routes.xml file and I can't see anything out of the ordinary. I've also tried to move the module into another folder (app/code/testimagecategory/CategoryImage/) and changed all of the references from /SR to /testimagecategory however it didn't work.</p>
  
  <p>Has anyone ran into this issue before? </p>
  
  <p>Any help is greatly appreciated! </p>
