Auth0 relaystate

I’m working with client that I’m sso into from auth0. I have my application create in auth0 as SAML2 web app. I’m able to get to them correctly with all my parameters but get an error from them stating “Unspecified relay state not supported for wildcard customer domain url”. Can anyone help with this type of error. I specifically don’t know where in configuration where to put the url that should be used as the relay state url.
