title: Spring boot 2.1 error.html page not showing
body: <p>I'm using spring-boot 2.1.3 and I want to add an error page as a fallback. I tried adding an error.html under the templates folder but it didn't work.</p>
  
  <p>Also tried to add ErrorController and classify a page for each error type and it didn't work either.</p>
  
  <p>Are there any other configurations that I should make?</p>
  
  <p>Thanks in advance.</p>
