Drupal 8: Mismatched entity and/or field definitions
<p>While trying to understand why my view is not displaying, I noticed the following error in the log:</p>

<p><a href="https://i.stack.imgur.com/k78VX.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/k78VX.png" alt="enter image description here"></a></p>

<p>I do not think it is possible to delete the URL alias from Taxonomy terms. At least I cannot find how to do this. 
I have, however gone through ALL of my taxonomy terms and removed the value for this field. </p>

<p>I have also done the following with Pathauto:

<p>Also, I have checked the report located at admin/reports/fields and can confirm that there are no entities that use a field called URL alias.</p>

<p>I have gone through each content item and ensured that they have the following setting (anyone know how to do this in bulk?). But still the error remains.

<p>Anyone know then how I can fix this strange error?</p>
