[keycloak-user] Getting parsing error while posting client_assertion in Keycloak 2.2.1.Final (Offline Access)

Hi Team, We are using Keycloak Tag 2.2.1.Final for our sample code for offline access flow through signed JWT, where we are passing offline_token (refresh_token) as "client_assertion" through JWTClientCredentialsProvider API call. We are getting "Parsing error" at Keycloak end (JWSInput.java) as I could see Keycloak API is parsing client_assertion as (parts.length < 2 || parts.length That means refresh_token parts should be less than 2 or greater than 3, but the client_assertion which we have is always has 3 parts (i. header, ii. payload and iii. Signature). Could you please suggest what is the significance of above mentioned logic. Or is there anything we are missing in "client_assertion". -- *With Regards, Jyoti Kumar Singh*
