As the error explains the 1st input to apply() must be a rule or function not simply a variable. Check out the docs

The apply function takes a function reference and an array - you've provided a user object and an array - ie the wrong parameter types.

I got same error for the below code also.

fn!apply(fn!append({},ri!username),enumerate(ri!RoleCount))

Also tried by creating separate rule for fn!append({},ri!username)
