Whenever i am refreshing the page Its throwing me error

I Am using keycloak server in angular.
whenever i am refreshing the page url It’s Throwing Me error That invalid parameters

How to achieve this.
Please give me advice or provide any documents if you have any.

Thanking You.

Usually that error comes when you specify no redirect_uri, or one that is not listed in your client configuration. Can you give us more information on your setup, so we can help you debug?

you should add http://localhost/* in the Valid Redirect URIs of your gumu client.

I Tried the same and it’s worked for me thank you.

Can you please advice me on this topic
