Hey Zendesk team!

We are migrating from GET to POST as all here. I was able to make this work even by sending it via the following form:
 

Hello Zendesk Support!

I have an issue on your side that prevents me from implementing SSO on React app with HashRouter.

I have URL like this: `https://localhost:3000/#/sso/zendesk` for both SSO Login and SSO Logout.

Everything works fine until an error appears. Let's say JWT is wrong. In this case Zendesk redirects me to the SSO Logout URL. Here the thing - when it does it, for some reason it URLEncodes my hash route and redirects the user to something like:

`https://localhost:3000/?kind=error&message=JWT+signature+invalid.+The+signature+cannot+be+verified%2C+check+that+your+tokens+match%23%2Fsso%2Fzendesk`

So no more hash route in the URL so the app does not recognize the route. This is only happening when kind=error.

Seems like a bug? Any thoughts?
