  <p>I am using springdoc-openapi-ui to render my API schema. This is the version details of it.</p>

  <p>Now, i have done some configuration in my spring boot application like below
  <a href="https://i.stack.imgur.com/9gvwA.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/9gvwA.png" alt="enter image description here" /></a></p>
  <p>Now, i was expecting that when i hit <code>localhost:15041/swagger-ui.html</code>, it should take me to <code>http://localhost:15041/swagger-ui/index.html?configUrl=/v3/api-docs/swagger-config</code> by default this and render my API document but unfortunately it only renders the Petstore. Even if i directly go to <code>http://localhost:15041/swagger-ui.html?configUrl=/v3/api-docs/swagger-config</code>, it doesn't render using the swagger-config.

  <p>Although if i go to <code>localhost:15041/v3/api-docs</code> i get my json API documentation and <code>localhost:15041/v3/api-docs/swagger-config</code>, i get the swagger-config.
  Also, if i enter <code>/v3/api-docs</code> in the Explore search area of the petstore page, it shows my API documentation.</p>
  <p>I have spent more than 1.5 days to fix it but it just doesn't work. Really appreciate if someone can help.</p>
