Hey everyone, trying to work through this error. If anyone can shine some light that would be great.
```error=invalid_request&amp;error_description=The+request+is+missing+a+required+parameter%2C+includes+an+invalid+parameter+value%2C+includes+a+parameter+more+than+once%2C+or+is+otherwise+malformed.+The+%27redirect_uri%27+parameter+does+not+match+any+of+the+OAuth+2.0+Client%27s+pre-registered+redirect+urls.```

Hi! You need to compare `redirect_uri` parameter in `/oauth2/auth` request (you send it to Hydra when trying to authenticate) with what value you specified in `redirect_uris` when you created client in Hydra

To list created clients in Hydra use <https://www.ory.sh/docs/hydra/cli/hydra-clients-list>

Once I realized how descriptive the error_description query parameter value was, it was actually super useful. There's a whole lot of noise in the URL that makes it seem a lot more complex and opaque than it really is. Does anyone know what the intent is of having what seems like the same generic error_description prefix? I've found that it's really just the last 1/3 of the value that has meaningful information in it.
