Creating Team Memberships in Appwrite for a Multivendor Application

I'm developing a multivendor application that allows users to create groups and assign different roles to members.
I'm using AppWrite's Teams API to manage the groups, but I'm having trouble working with memberships.
The documentation doesn't seem to match the actual behaviour of the API. Can you please provide guidance on how to create team memberships using the AppWrite server SDK? I have included screenshots of my function logic and a snippet of the error I'm getting when I try to invoke the function.

Sorry guys.
While digging up I realised that the event payload is passed as a string not an object. Therefore I had to first parse it into a JSON object then use the values in the json string. The team API works fine. Finally got the membership functional.

It worked but in the documentation it is saying that the email option is not optional when creating a team if argument is passed as an empty string.
There is need to fix this in the documentation.

I'll raise an issue

How can I raise it anyway

You can create an issue on GitHub: https://github.com/appwrite/appwrite/issues

However, before you do that, it looks like you're using the SDK and referring to the docs for Appwrite version 1.3.x, but your Appwrite is version 1.2.1

Please upgrade (https://appwrite.io/docs/upgrade) and try again

Thanks.
