500 Server error for HTTP POST "/refreshtoken"

I am using the same end point for the refreshtoken action as given in this repository but,
When the refresh token is expired and we are supposed to get 403 FORBIDDEN, I am getting 
This error: 
ERROR o.s.b.a.w.r.e.AbstractErrorWebExceptionHandler - Could not resolve parameter [1] in public com.myprojectname.Exception.ErrorMessage .....
No suitable resolver.

Can someone please help me?
