Uncaught Invariant Violation error in console

The console shows an error that doesn't seem to have consequences on the site:

Uncaught Invariant Violation: Minified React error #37; visit http://facebook.github.io/react/docs/error-decoder.html?invariant=37 for the full message or use the non-minified dev environment for full errors and additional helpful warnings.

The proper fix would be to use swagger-ui-react, which addresses this very problem.

Problem is swagger-ui-react doesn't support custom plugins and that's the whole point of our Swagger integration.

Pushing the issue back for now since the issue doesn't seem to have any practical effect on the user experience.

@bfabio I've found the cause of the problem but unfortunately at the moment, I don't have a solution.

The warning is due to the fact that here the element #swagger is not present in the dom.
