CAS 6.0x /oidc/accessToken api issue

[Tibin Abraham]

CAS : 6.0.x

HI team,

I am using /oidc/accessToken api for generating accessToken for automation purpose.

API : /oidc/accessToken

body content type : application/x-www-form-urlencoded

body :

grant_type         : password

username            : <username> 

password            : <password> 

client_id               : <clientid>

client_secret       : <client secret key>

when I decode the the token , the "preferred_username" in claims is coming as an array instead of String which is causing an issue.

Could you please suggest what I am doing wrong.

Thanks in advance,

TIbin
