SSO configuration using openidc : OpenID Connect Redirect URI with no parameters

Error:

Invalid Request
Description:

You’ve hit an OpenID Connect Redirect URI with no parameters, this is an invalid request; you should not open this URL in your browser directly, or have the server administrator use a different OIDCRedirectURI setting.

I’m using this URL : OIDCRedirectURI https://{domain_name} … as I make the root at nextcloud app
