ArgumentError: invalid value for 'platform', must be one of ["ios", "android", "web", "other"].

I am using the AppUser Update:

https://github.com/smooch/smooch-ruby/blob/master/docs/AppUserUpdate.md

It doesn't require platform nor explain how to add it, but I keep getting this error above, using code same as the documentation and it breaks:

api_instance = SmoochApi::AppUserApi.new
app_user_update_body = SmoochApi::AppUserUpdate.new
app_user_update_body.properties = json
result = api_instance.update_app_user(user_id, app_user_update_body)
ArgumentError: invalid value for 'platform', must be one of ["ios", "android", "web", "other"].

ArgumentError: invalid value for 'platform', must be one of ["ios", "android", "web", "other"].

The payload being sent contains the platform. I have a feeling it's rejecting "messenger":

Let me see if updating the gem helps:
