7.0.0-SNAPSHOT - {"error":"invalid_request","error_description":"Unsupported prompt parameter value"}

[G Lalonde]

I'm encountering the following error returned on the display

{"error":"invalid_request","error_description":"Unsupported prompt parameter value"}

which I suspect is related to the "prompt=select_account"  element for the following oidcAuthorize call

 

https://secure.redacted.org/cas/oidc/oidcAuthorize?response_type=code&client_id=xdXOt13JKxym1B1QcEncf2XDkLAexMBFwiT9j6EfhhHFJhs2KM9jbjTmf8JBXE69&redirect_uri=http://127.0.0.1:35609&code_challenge=b2aWeUfrEOhgtnGo-fIIFhnTh7aQpbgV9ok6Mqj4V8g&code_challenge_method=S256&scope=openid%20offline_access%20email%20profile&prompt=select_account%20consent&state=mwSZmzjqG8A1kk0LUFBmKInumXw79WXgTjSkSL5ctjA%3D&login_hint=john&user=john

I've tried specifying different values in the cas.properties file such

cas.authn.oidc.discovery.prompt-values-supported=none,select_account

but to no avail.

I've had to revert to my 6.5.2 version to avoid this roadblock.

Thanks.
