title: Magento 2 - Error: Attribute with attributeCode “X” does not exist
body: <p>I have created a new attribute for a product and added that to the default attribute set. When I then click to navigate to Products > Catelog so that I can implement the attribute, I get the following error:</p>
  
  <p>Attribute with attributeCode "X" does not exist.</p>
  
  <p>Any suggestions on how to resolve that?</p>
